I have never had any problems as the software constantly updates its database every time you use it from iblocklist.com. iblocklist is an up to the minute list of all known blacklisted ip's. Also you can manually add any ip's to the block if desired. If you torrent, the program is very effective as it blocks all known law enforcement agencies.
Ahhh, ok then. I went to iblocklist.com and have to give them props for the extensive and thorough listing of blocked ip's. Truly impressive. It sounds like PeerBlock offers up an easy to use block list capability, as well, from reading their site. Didn't think of the torrent side of it and now that I have I'm downloading PeerBlock. Thanks for posting! Edit: Does it mistakenly block sites that you'd normally go that don't have any issues that would warrant PeerBlock blocking the ip?
Good to know. I don't use Tor, but I do like to torrent shows once in awhile.
