That's because captcha doesn't stop bots but it does inconvenience real users. Faucets use them as it imposes a cost that makes it less profitable to bot. For spambots here I don't think ~$0.001 per post would deter them.
Yeah, I know but there should be another solution, there are some good alternatives to reCaptcha as well. Idk what theymos is planing for the new forum software but there should be some kind of a solution to this problem. Reporting the single accounts is just, as we say, " a small drop into the ocean". There should be a general solution with the minimum impact to the regular users, I know it's difficult...
