It would be preferable if you would lie less. Evil pirate uploads potentially_infringing.mp3 to to filehost. Filehost actually serves potentially_infringing.mp3, a community on db0 hosts a link to potentially_infringing.mp3, lemmy.world caches locally a copy of data from db0. Of those the one guy directly uploading the information is at risk of an extremely unlikely single digit thousands of dollars.
Nobody not even evil pirate himself is at risk of decades in prison or millions in debt. Companies responsibility basically ends at taking stuff down when specifically notified of infringing content.
