Hi all,
I recently got an email from my cable company saying that I'm being monitored and warned for copyright infringement or something. Basically, they told me to stop downloading stuff.
If they didn't send you a copyright violation with this warning email then it could be fake or your ISP just doesn't forward those notices. Maybe it was just that your p2p traffic is really high and they were able to spot your download activity.. Hard to say.
I doubt they have time to sit around monitoring all what you are doing along with everyone else..

I use frostwire and bittorrent, thats about it. Has anyone ever gotten this before?
Lots of people have gotten letters forwarded to them by their ISP for copyright violations etc .. you haven't really given any example of what you recieved for people to know if they have got the same warning as you.

Are they really monitoring my computer?
Unlikely, but you never know. The way it usually works is that the copyright holder hires enforcers or digital hitmen [ baytsp / media sentry etc ] to monitor their files or pump out decoys so they can get your IP address and then forward a warning off to your ISP.

I have PeerGuardian 2, and recently forgot to turn it on for all my downloads. Will using PG2 be sufficient enough to stop these guys from snooping around on my computer?
An IP blocker can only be as good as the IP's on it's blocklist. There is no 100% guarantee that you can block everything. Using BitTorrent also makes your possible identification a lot easier and a blocklist cannot protect you from that.
