Get a decent firewall, stop downloading from public trackers and forget about this crap.
PG supposedly blocks traffic to any known IP adress (RIAA, MPAA, companies that pursue copyright violations, etc.) - but for this PG has to know these IPs. These people are not dumb, they know about this issue, so they'll never use a "burnt" IP again. Next point is, once they got your IP from a tracker... well, they actually have your IP. It doesn't matter if you'll never connect to them, they have your IP, that's all they're interested in to file a complaint at your ISP.
PG does *nothing*. It's just a placebo to make you feel safe. Again: not downloading from public trackers (Pirate Bay, Demonoid, etc.) is the best thing you can do to be safe.
