If all they have to go by is IP address, what do they do in, say, my case? I'm on ADSL and the IP the outside world sees is rotated pretty regularly. Would my ISP even be tracking what it is? I would think that sort of thing is heavily automated. Would they bother to log all that information? If they scan for more information I'm heavily firewalled so any scan would turn up zip.
I don't use any of the knutella clones some I'm pretty safe for now (I think ) but in the future....
