Actually, I just did a cursory google search on a few of the more unique looking names, and they come up all over the internet. One of them is definitely not too worried, their pseudonym is also registered on a bestiality/zoophilia forum as well as some overclocking forums. I think this is definitely enough information to nail some of these people, with the right investigation.

No guarantees though, choosing an existing handle/username with a tarnished reputation seems like a pretty good strategy to me for online shenanigans.
