(note that it's not related to the script in this gist) timfam. I've plugged your blocklist url into transmission and it has. Egrep -v '^#' >~/torrent. 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?]. Welcome to I-Blocklist! Vuze, Transmission, uTorrent and, pfBlocker. You can view the lists that we distribute on the lists directory page.

Is, in my opinion, the best BitTorrent client for OS X and Linux [and did you know there’s even an unofficial too?]. Because it’s super easy to use and configure and it’s not resource-hungry like some other one [someone said 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. Citizen Calibre 3000 Manual. If you search on Google you will find people recommending 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.

Luckly, a user from quora.com, created a which combines all those iBlocklist lists in to a single one and he hosted the result here: 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.

If this post was useful to you feel free to 🍺! Thank you really much.

Typically block lists in torrent clients are there to block any clients that show 'abnormal' behaviour against your client - such as, too many connections per second, invalid connections amongst many others. Although, I do not know about Transmission, some torrent clients have features of build in which blocks known IP's that belong to law agencies and companies that are employed to attack, leech, infiltrate or sue users of P2P networks.

Can it slow down? Port Blue The Airship Zip there. Yes, probably, you may not be getting connections from clients capable of sending data - however, one of the items that it blocks is people sending repeatedly corrupt or invalid data, so it is not necessarily a bad thing.

Blocklists generally block IP addresses belonging to companies that try to either track bittorrent users or send them bad data. From what I've heard, they're useful as protection against tracking (and getting infringment letters), but the main reason to use a blocklist is that they generally speed up your downloads. The reason is that some companies run bittorrent clients with intentionally bad data and try to share it. Your client will automatically discard it, but it will slow you down. Your client will also eventually block them even without the blocklist, but it's faster to just block them from the start. EDIT: So here's about how blocklists are helpful as protection against tracking (TorrentFreak suggests that if you're not using a blocklist, you're being tracked).
