Figured I'd start a topic for which to list all those lame fuckers who waste our bandwidth with bad files.
I'll start off with 2:
Johnmw6@kazaa (was unable to isolate his IP)
NiaPoly712@kazaa (22.214.171.124, no NS specific to the IP, but owned by Cogent Comm) -- This one is in DC (no surprise)
I'll post more as i find them
