Whilst I agree that PeerBlock is mostly unnecessary when using Bitcoin, It may become increasing more useful as the Bitcoin network expands.
It would even be possible to create a 'Bitcoin blocking list' for know 'bad nodes'.
The 'default' blocking lists are mostly outdated and excessive, I agree. It's important to use the correct 'blocking lists' for your activity and to create your own custom lists. You can simply use it as powerful addition to your firewall. I often use it on my windows PC to help block Microsoft.
Here is a better custom list source: I-Blocklist - http://www.iblocklist.com/lists.php
@ aceat64. Maybe try using Tor ( or another proxy system ) and always delete all trackers before you connect ( only works with DHT, etc. ofc).
P.S. I realize this upsets some Tor exit node operators, although as Torrent clients like Vuze incorporate Tor usage options (and I have also run an exit node) I don't see much of a problem with it. Just respect the exit node operators with acceptable usage.
