PLEASE! These don't click/Click me bots are annoying. My friend Zombie Rude Wolf ##### up a bot username called read my desc. Please just ban them. They mostly spam friend requests to the poor (idk maybe?) PLUS ignore the friend requests!
I don't know about you, but considering the amount of computers used to generate the bots, it's pretty much impossible to prevent bots. The only way would be to add a stronger CAPTCHA, but that probably wouldn't work either.
