So this evening, I got a bit of marketing from Telstra. This was to an email address I had used to register the SIM card that I’m trying out in the Kite. I naturally followed the same approach I have with other such suppliers as an anti-phishing tactic.

The email is not unsolicited, but it is a commercial email nonetheless. I figured I’d just quietly opt-out, no need to make a fuss. The email itself was legitimate, so no concern about boobytrapped unsubscribe links. Naturally, I copied the address from their email and paste it into the form on their webpage. I get told this:

Errm, excuse me? That is the email address that I wish to unsubscribe, and if it were invalid, I would not be trying to unsubscribe because I would not have gotten the email in the first place!

Okay, so I’ll need to go through a human to get this resolved, what joy. Navigate the labyrinth that is the Telstra support site (they really don’t want you to be able to make complaints), and I get to a complaints form. First thing I note, they forgot to close an <a> tag (end of line 154)…

<p>If you require immediate assistance with a complaint, <b>Consumer customers</b> can call us anytime on 132200 and say "complaint".<br><br>
If you are a <b>Business customer</b> and require immediate assistance with a complaint, you can call us anytime on 132000 and say "complaint".</p>

<div id="surveyContentDiv" class="content-background">

As a result, Firefox thinks everything to the end of the form, is part of the link! They also close a tag that isn’t open: <pre>.

UPDATE 2018-07-07: This has now been fixed.

Right, so there’s two things. I persevere with the form, resorting to keyboard shortcuts since clicking on any form element brings up that PDF.

Happy that I’ve covered what I wanted to say, I hit the submit. Only to find out the same person who designed the last form, must have designed this one too.

Great, so that’s now three things to complain about.

What really saddens me with Telstra is that today their management tell us they “aspire to be a technology company”. The fact that years ago, Telecom Australia was very much a respected member of the ITU meant it pretty much was a technology company… and the fact they can’t get something as basic as email address validation or a simple web form right, really does show how far they have fallen.

I fully expect this will go back-and-forth while they ask for my browser details (irrelevant, this is broken HTML at their end), my OS (again irrelevant), and then the claim that: “Ohh, we don’t support that!” Which will hold about as much water as a tissue paper G-string.


So, an update. I had a reply back, basically they stated a few things:

  1. they claim to not have seen any marketing emails for the past two months sent to me. (how hard did they look?)
  2. they claim to have taken my name off the list (we’ll see)

They make no comment about fixing the forms. The complaints form now has its closing </a> tag back, so clicking on form elements no longer causes it to pop up with a PDF download. Great, 1 problem of 3 fixed.

I finally had a moment to reply, and did so. In their email, they give an address to send the reply to (because we’re to cool to set the Reply-To header or use the correct From address):

I got back an immediate response:

Oops… so there’s another complaint:

I note there’s another address (with an ‘s’ on the end) in the footer of the email, and so I have sent them the following:

Hi,
It's taken a little while to get back to you on this as I've been flat
out, but here goes.

To be clear, the issue is not with the mobile service itself, that's
been fine for the purpose I've used it. The issue is in the marketing
that came with it, that was unwanted.

Yes, this is correct. It might be polite to ask people when they sign
up whether they want to be on this marketing list or not.

In my case, the service is temporary: I have the loan of a prototype
mobile phone: iSquare Mobility Kite v1.

http://www.kiteboard.io/ is the device being trialled.

The manufacturer has loaned it so that I can trial the device on the
Australian mobile networks, and see how it performs in weak-signal
conditions. I have loan of it possibly for another month or so at most.

(So far, it performs *MUCH* better than the ZTE T83 I use, and holds its
own against the ZTE T84 which uses the same chipset as the Kite.)

I'd have used my own SIM card, but my card is too big to fit in this
phone (mine is a miniature SIM, this phone requires a micro-SIM), and
given its temporary custody, it made no sense to get my existing Telstra
service moved to a new SIM.

Thus for this purpose, I just activated a pre-paid service to be able to
try the device out. I also have a service activated with Optus as it's
a dual-SIM device.

Once iSquare Mobility ask for the return of the device, naturally I'll
have little use for the two pre-paid SIM cards that are presently in it,
and won't have any interest of any offers from Telstra (or Optus).

I have an old 3G phone I can possibly use up the remaining credit of the
Telstra SIM in, otherwise I'll just use my current phone service which
I've had since 2001.

Allow me to present exhibit A; sent Thu, 28 Jun 2018 00:39:53 -0700.
This is attached.

I'm a little surprised your list management software had trouble finding
it, unless of course, you didn't read the complaint message carefully to
see the address my account was *actually* registered under.

I see you don't mention the issues with the form. One issue makes the
form damn-near unusable for anyone due to malformed HTML causing the
entire form to act as a hyperlink to the complaints information PDF.

The other, prevented me from self-unsubscribing and was the reason for
the complaint in the first place.

Don't worry, the world already knows:
Telstra: another mob that didn’t get the RFC5233 memo
I see the missed tag on the complaint form has now been corrected. The original issue that started this, so far has not been corrected. I've attached screenshots for your reference. > We know you've been put out by this matter so we'd like to fix things > by: > > * Confirming the medium of marketing (SMS, Email, phone call, MMS, > face to face marketing, etc) and date you received it This is email marketing.

Yep, I understand this. This is a silent number, and a temporary one at that. By Christmas time, this service will be no-more, as it will be surplus to requirements. > If you’d like to talk more about this or accept this offer, please > contact me on 1800 241 787* PIN 5172 or email > ComplaintResolutionCentre@team.telstra.com quoting your Telstra > reference SR x-xxxxxxxxxxxxx number.

I've attached the bounce message I received, and have also submitted it as SR x-xxxxxxxxxxxxx just in case this email doesn't get through. So that's now 4 issues in total, with 1 resolved so far. If you could fix up the broken email validation on the opt-out form and complaints form, and fix the broken email address in your reply messages then that will resolve the remaining issues. Thanks in advance. Regards, -- Stuart Longland (aka Redhatter, VK4MSL) I haven't lost my mind... ...it's backed up on a tape somewhere.

So, recently I bit the bullet and decided to sign up for an account with AliExpress.

So far, what I’ve bought from there has been clothing (unbranded stuff, not counterfeit) … while there’s some very cheap electronics there, I’m leery about the quality of some of it, preferring instead to spend a little more to buy through a more reliable supplier.

Basically, it’s a supplier of last resort, if I can’t buy something anywhere else, I’ll look here.

So far the experience has been okay.  The sellers so far have been genuine, while the slow boat from China takes a while, it’s not that big a deal.

That said, it would appear the people who actually develop its back-end are a little clueless where it comes to matters on the Internet.

Naïve email address validation rules

Yes, they’re far from the first culprits, but it would seem perfectly compliant email addresses, such as foo+bar@gmail.com, are rejected as “invalid”.

News to you AliExpress, and to anyone else, You Can Put Plus Signs In Your Email Address!

Lots of SMTP servers and webmail providers support it, to quote Wikipedia:

Addresses of this form, using various separators between the base name and the tag, are supported by several email services, including Runbox (plus), Gmail (plus),[11] Yahoo! Mail Plus (hyphen),[12] Apple’s iCloud (plus), Outlook.com (plus),[13] ProtonMail (plus),[14] FastMail (plus and Subdomain Addressing),[15] MMDF (equals), Qmail and Courier Mail Server (hyphen).[16][17] Postfix allows configuring an arbitrary separator from the legal character set.[18]

You’ll note the ones that use other characters (e.g. MMDF, Yahoo, Qmail and Courier) are in the minority.  Postfix will let you pick nearly anything (within reason), all the others use the plus symbol.

Doing this means instead of using my regular email address, I can use user+secret@example.com — if I see a spoof email pretending to be from you sent to user@example.com, I know it is fake.  On the other hand, if I see someone else use user+secret@example.com, I know they got that email address from you.

Email validation is actually a lot more complex than most people realise… it’s gotten simpler with the advent of SMTP, but years ago …server1!server2!server3!me was legitimate in the days of UUCP.  During the transition, server1!server2!server3!user@somesmtpserver.example.com was not unheard of either.  Or maybe user%innnerhost@outerhost.net?  Again, within standards.

Protocol-relative URIs don’t work outside web browsers

This, I’ve reported to them before, but basically the crux of the issue is their message notification emails.  The following is a screenshot of an actual email received from AliExpress.

Now, it would not matter what the email client was.  In this case, it’s Thunderbird, but the same problem would exist for Eudora, Outlook, Windows Mail, Apple Mail, The Bat!, Pegasus Mail … or any other email client you care to name.  If it runs outside the browser, that URI is invalid.  Protocol-relative means you use the same protocol as the page the hyperlink exists on.

In this case, the “protocol” used to retrieve that “page” was imap; imap://msg.aliexpress.com is wrong.  So is pop3://msg.aliexpress.com.  The only place I see this working, is on webmail sites.

Clearly, someone needs a clue-by-four to realise that not everybody uses a web browser to browse email.

Weak password requirements

When I signed up, boy where they fussy about the password.  My standard passwords are gibberish with punctuation… something AliExpress did not like.  They do not allow anything except digits and letters, and you must choose between 6 and 20 characters.  Not even XKCD standards work here!

Again, they aren’t the only ones… Suncorp are another mob that come to mind (in fact, they’re even more “strict”, they only allow 8… this is for their Internet banking… in 2018).  Thankfully the one bank account I have Internet banking on, is a no-fee account that has bugger all cash in it… the one with my savings in it is a passbook account, and completely separate.  (To their credit though, they do allow + in an email address.  They at least got that right.)

I can understand the field having some limit… you don’t want to receive two blu-ray discs worth of “password” every time a user authenticates themselves… but geez… would it kill you to allow 50 characters?  Does your salted hashing algorithm (you are using salted hashes aren’t you?) really care what characters you use?  Should you be using it if it does?  Once hashed, the output is going to be a fixed width, ideal for a database, and Bobby Tables is going to be hard pushed to pick a password that will hash to “‘; drop table users; –“.

By requiting these silly rules, they’ve actually forced me to use a weaker password.  The passwords I would have used on each site, had I been given the opportunity to pick my own, would have featured a much richer choice of characters, and thus been harder to break.  Instead, you’ve hobbled your own security.  Go team!

Reporting website issues is more difficult than it needs to be

Reporting a website issue is neigh on impossible.  Hence the reason for this post.  Plenty is there if I want to pick a fight with a seller (I don’t), or if I think there’s an intellectual property issue (this isn’t).  I eventually did find a form, and maybe they’ll do something about it, but I’m not holding my breath.

Forget to whitelist a script, and you get sworn at, in Mandarin

This is a matter of “unhappy code paths” not receiving the attention that they need.  In fact, there are a few places where they haven’t really debugged their l10n support properly and so the untranslated Alibaba pops up.

Yeah, the way China is going with global domination, we might some day find ourselves having to brush up on our Mandarin, and maybe Cantonese too… but that day is not today.

Anyway, I think that more or less settles it for now.  I’ll probably find more to groan about, but I do need to get some sleep tonight and go to work tomorrow.
