Wondering if Rick has any control over the sign-up questions, but they're fairly bogus. Example:
First of all, a serious answer would be 'spammer'. So I was wrong on first try.
'dog' was wrong on the second try.
'a spammer' was wrong on the third try.
...and I finally got it with 'a dog'. I doubt many new users would run that gauntlet 4 times; the site is probably barring a lot of new users, and I don't mean spammers.
These questions are just bad, plain and simple. The answer is logically wrong, frustratingly exact ("a dog" not just "dog") and worse yet, it's static. As in, it appeared first every time I tried to sign up. I don't know how many questions there are, but it doesn't seem good. Failing this question always brought up a question asking the difference between 3:15 PM and 8 PM in hours, which didn't accept "4" or "4.25", maybe it wanted "4 hours" or "4.25 hours" or "4 hours and a quarter", who knows. Either way, awful questions.
Thanks for reading this! I do hope the questions can be replaced to be guessable to humans, or removed.
