how much liability (under us law) do you think peertube servers would have for seeding copyrighted content?

or, what if the server had a rule against seeding those videos, but because of how small the mod team is, took a day or 2 to catch them?

it's obviously much more risky than just a tracker since it would act sort of like a seedbox with a public player, so wouldn't it be considered a distributor if caught?
