I’ve found that the block lists on the net tend to contain extremely outdated information and blocks a lot of legitimate activity, while ultimately being ineffective at actually blocking copyright trolls sufficiently. Best to have a vpn to prevent that. Since I have a vpn, I don’t care who downloads from me so long as they aren’t abusing my resources. So I manually create a blocklist for IP blocks I’ve observed malicious activity from. The blocklist file syntax is a note and an IP or IP range (not cidr notation) on each line, separated by a colon. for example, to block 195.154.0.0/16:
(That’s an IP range I actually block, belonging to poneytelecom, a very low reputation hosting provider I was getting some weird denial of service looking activity, like 40+ simultaneous connections who wouldn’t actually download anything)
Also, if you download torrents popular in China you may come across the Xunlei client, which always reports its progress as 0% and never seeds. Banning these would be impractical game of whack a mole. So instead, simply enable super seeding mode on those torrents. Gone instantly. Might be slower at seeding, but at least now you can seed to legitimate users.
