The Mosquito Crate: a CAPTCHA Exclusively for Spammers
This summer, our forums were inundated with spam. Lots and lots of spam. Because I can't mail the spammers a crate of mosquitos, I made a CAPTCHA that only they can see, and that can't possibly be answered correctly.

The answers are taken from a Markov chain through the rules for the Pathfinder roleplaying game. No matter what the spammer enters, their answer will be wrong. And it'll tell them in detail why.

(Unless they are presented with a random error code corresponding to a monster with a sock on its back. If you get one of those, just refresh the page.)

Only accounts identified as spammers are sent to the CAPTCHA, but I figured others might be amused by it, so here we are.

I dunno if it's deliberate, but the "request another" and "submit" button labels keep swapping places, but the buttons' functions do not.

Pretty much everything about that page is deliberate. I had to restrain myself from putting in randomly malformed HTML to mess with the spammers' browsers. The input box will change size and there's some extra random hidden elements just in case someone's writing the parser for a bot.

I guess what I'm saying is, this is what you get when everybody leaves for Gen Con and I've finished my todo list.

Great idea. Death to all spammers. I found that requiring newly registered users to make an initial post on a subforum only they can see has saved me hours of killing spammers by hand. If you want to see this in practice, register here:
