Do not use PeerBlock or PeerGuardian

They are snake-oil and do not protect you. Instead, they blacklist our tracker, alongside thousands of seedboxes and other harmless random addresses.

Get rid of this crap. If you want to protect yourself, get a VPN. We have informative threads on VPNs in our Help subforums.
