Sometimes I think that these sorts of stupid, wrong, validation are the fault of idiot managers. When it's apostrophes though I'm suspicious that it may be idiot programmers who don't know how to prevent SQL injection attacks without just saying "ban all apostrophes everywhere". Or perhaps it's idiot "security consultancies" who make it a tick-box requirement. > OK, now that I am started, what else? Oh yah. Look at your credit > card. The number has spaces in it.

Does nobody who works for the companies making these sorts of websites ever use their own, or indeed anyone else's, website? Another one that's become popular recently is the sort of annoying website that insists on "email 2FA", i.e. you try to login and then they send you an email with a 6-digit code in that you have to enter to authenticate yourself. So you go to your mail client and double-click on the number to select it, and stupid thing (A) happens: for no sane reason, the computer selects the digits *and also an invisible space after them*. Then you copy the digits into the web form, then invisible space tags along for the ride, and stupid thing (B) happens: the web server rejects the code because of the trailing space. Honestly I don't understand why every web application platform doesn't automatically strip all leading and trailing whitespace on user input by default. It's surely incredibly rare that it's sensible to preserve it. (I see Django eventually got around to this in version 1.9.) -- https://mail.python.org/mailman/listinfo/python-list
