On my forums I am noticing a lot of new signups. However, they never post. For example, search the username "neabyzteplz" in Google. Something like 13,000 and all forum usernames, same with these other names. So I think someone is messing around, about to do a TON of massive spam on forums all across the internet all at once. Once you have a list of various usernames and passwords from forums all over, it would be easy enough to write scripts to go about this several ways.
Maybe this has already been noticed and some sort of counter-measure hack released... I dont know. The only thing I can think of that would prevent it is an image verification to submit posts. Anything like that already written?
