The Transmission torrent client has an option to set a Blocklist, which helps protect you from getting caught and having the DMCA send a letter/email.
It's as simple as downloading and installing the latest client:
After installing, navigate through the menu: Edit > Preferences > Privacy:
Thank you to everyone who has contributed to this list, I am grateful for your efforts.

This seems to work quite well: https://github.com/fonic/ipfilter
Only downside is that you need a server to provide the file as Transmission still hasn't implemented support for local blocklist files. I put the script on my NAS, which generates the block list and then serves it to local clients via HTTP. Works perfectly thus far.
here is something i hacked together using the iblocklist.com list. of course i ended up registering to iblocklist.com to get this to work. replace with your own custom url they provide you based on your selection etc... also worth noting i run transmission in a docker and extract the blacklist file to my container config / blacklists folder then restart the container for it to read it on startup. then i just cron the below script weekly.
`#!/bin/bash
URL='http://list.iblocklist.com/?list=xyz&fileformat=p2p&archiveformat=gz&username=meh&pin=1234'
OUTPUT_DIR='/mnt/nfs/swarm/dockervolumes/transmission/blocklists'
OUTPUT_FILE='blocklist.gz'
EXTRACTED_FILE='blocklist'
DOCKER_CONTAINER='transmission'
wget -O $OUTPUT_FILE $URL
gunzip -f $OUTPUT_FILE
mv $EXTRACTED_FILE $OUTPUT_DIR/$EXTRACTED_FILE
docker restart $DOCKER_CONTAINER
echo "Blocklist updated and Docker container restarted successfully."`
in September 2024, this link https://github.com/Naunter/BT_BlockLists/raw/master/bt_blocklists.gz still works. Thank you!
Yes, "https://github.com/Naunter/BT_BlockLists/raw/master/bt_blocklists.gz" still works and the date changes routinely, but it doesn't appear the contents of the file have changed since 2022 or earlier. The scripts creating the archive are running, but it's unclear if there are actually any updates to be had, let alone included.
@Zotter try https://raw.githubusercontent.com/Naunter/BT_BlockLists/master/bt_blocklists.gz cause that other url goes through several 30x
I did wonder if @Zotter has a point though, @engineeror . If it's true the contents haven't changed in a while, I'll update the gist with that warning information. I haven't been paying attention (or even using transmission)
@Zotter I replaced the URL in the gist yesterday when @engineeror pointed that out, I notice that you mentioned the original had one more URLs. Now I don't know if I should restore it! But also, I wondered if things get pruned.
well in my case i noticed that the blocked IP count doesn't change in transmissiond with https://github.com/Naunter/BT_BlockLists/raw/master/bt_blocklists.gz anymore.
apparently several redirects are now needed via that url to get to the archive and transmissiond doesn't handle this properly i guess.
currently end url is https://raw.githubusercontent.com/Naunter/BT_BlockLists/master/bt_blocklists.gz and with this the blocked IP count is now changing for me again.
idk if transmissiond updates automatically, so i have this:
# /etc/systemd/system/transmission-blocklist-update.service

Just wanted to say that I've been using the former url for quite a while and it's been updating the blocklist weekly for me. I just did a manual update and the count changed from 453,xxx to 452,834 rules. This suggests the app is able to handle redirects for that url. But since you claim the latter url is more direct, I've gone ahead and used that one.
Transmission 4.0.6
For the record, both URI work for me, and as of today 2025-05-06 both have 455,833 IPs.
By "both URI" I am referring to https://raw.githubusercontent.com/Naunter/BT_BlockLists/master/bt_blocklists.gz and the original URI https://github.com/Naunter/BT_BlockLists/raw/master/bt_blocklists.gz. No issues with either.

Yep, using it with 5.1 right now.
It works for Transmission 4.0.6 (38c164933e) as of September 12, 2025, and shows 456,022 IP addresses blocked.
Ditto, using https://raw.githubusercontent.com/Naunter/BT_BlockLists/master/bt_blocklists.gz
Raw URL still OK as of 2025-10-03
It works! Great job, thanks very much!
Raw URL still doing great as of today (2025-12-13) for Transmission 3.00 (75db68a812) on OS X 10.9 Mavericks
Thanks for this. Still working as of this writing...
