Transmission is, in my opinion, the best BitTorrent client for OS X and Linux [and did you know there’s even an unofficial Windows version too?]. Why? Because it’s super easy to use and configure and it’s not resource-hungry like some other one [someone said µTorrent for OS X?].
But it has a problem. Blocklists are damn hard to find.
Looking for a nice and complete blocklist for Transmission can be a pain, especially if you’re not sure of which one to pick. In fact there are a ton of lists all for different purposes and no one will give you complete bad-peer protection since one will shield your client from spammers, one from the US Government [really?] and no one from all those things combined.
If you search on Google you will find people recommending this website, called iBlocklist, which collects various block lists but there are to many of them and they all have the same problem I said before: no complete 100% protection.
simply add this URL in the Transmission preferences like this:
and the application will do all the magic for you combining the lists and adding those IP rules to the built-in firewall. Be sure to check the option below to make Transmission update the blocklist weekly for you so you won’t have to worry anymore. This works with all versions of Transmission and with all OSs.
