I would have thought the logic of CAPTCHAs is to have humans read text that bots can’t read…but not to practically solve an optical illusion puzzle. Here’s a CAPTCHA I ran into the other day – the second set of letters is, what…”Schulte”? “senmlte”? “scnlte”? I don’t even remember what I guessed now – I managed to get it right. Good thing you’re allowed to try again!
