Can You Write a Sure-fire Algorithm to Stop Bots?

Meh. Leave the drama bomb in the zoo. Withholding "ideas" that aren't implemented, and probably won't be implemented is silly. If the sites cared about the bot problem, if there is a bot problem, they would do something.

Off the top of my head I would think some kind of question written with the letters scrambled would be enough to mess up a bot. Not a captcha but a real, short answer question.
