An Anonymous quality analyst and audiophile accounted "As a returning customer at napalmrecords.com I was forced to update my Billing Address. Fine. Sure. But what if my *House number* is a very big number? More than 10 "symbols"? Fortunately, 0xDEADBEEF for House number and J****** for First Name both passed validation."
And then he proved it, by screenshot:
Richard P. found a flubstitution failure mocking "I'm always on the lookout for new and interesting Lego sets. I definitely don't have {{product.name}} in my collection!"
"I guess short-named siblings aren't allowed for this security question," pointed out Mark T.
Finally, my favorite category of Error'd -- the security snafu. Tim R. reported this one, saying "Sainsbury/Argos in the UK doesn't want just anybody picking up the item I've ordered online and paid for, so they require not one, not two, but 3 pieces of information when I come to collect it. There's surely no way any interloper could possibly find out all 3, unless they were all sent in the same email obviously." Personally, my threat model for my grocery pickups is pretty permissive, but Tim cares.
