British Airways is definitely not aware that it is 2017 already.
First of all, I've had it with them sending me their useless “Executive Club” emails (what possible use can I get from it?). Having received another one, I clicked the “unsubscribe” link.
It opened a page with an empty text field to put an e-mail into:
So, you couldn't pass it with the URL, could you? Well, I understand, you wanted to keep the URL clean and simple, but wait… OH SHI~
That's how this link actually looks like. Are you fucking serious? You've put a zillion IDs in this poor URL, but you couldn't pass an e-mail with it? Or get it on the server side with one of those IDs? You guys are unbelievable.
And they actually do have a clean URL (http://britishairways.com/unsubscribe/), which opens exactly the same web-form. So, what's the point?
But ok, no worries. I can copy-paste my e-mail. Here you go, I'm pressing Submit and I'm getting…
