Wait, so you can host a torrent site in the USA and not get your domain ceased by the FBI?
“Following the DMCA” is irrelevant to anything the FBI would be involved in.
If the DMCA allowed US operators to host torrent catalogs openly, there’d be a plethora of them.
Also its hard and extremely expensive to defend yourself to prove it in a niche specifically where people are looking not to pay making it harder to montize to defend properly.
Why do you think that is?
