The biggest problem with torrenting is that you not only download, but also upload. In most (actually all) cases of copyright infringement letters I know of it was about uploading.

While they could propably attack you for downloading, they can’t really prove any losses and if they do they will be so low that it isn’t profitable fot them to pursue you. The damages they want from torrenting is because you “multiplied” their work by uploading it to others.

And that would mean the piracy site logged your ip (which is likely considering how sketchy some sites are, but may also not happen) and law enforcement somehow got these ips (highly unlikely) and shared them with copyright trolls (I think because I don’t think law enforcement will go after small fish like that and prosecute you for watching Marvel without paying) and I don’t see why law enforcement would share them.

But I don’t know law and I just never heard of someone getting a letter from copyright trolls for downloading over http. I am in Germany BTW so it may be different in other countries
