DMCA is widely abused; it’s a knee-jerk corporate reaction, and by now most DMCA notices are probably being sent out by LLMs. Very likely, a substantial percentage are not even valid - either targeting content that the requester has no claim to, is falsely identified, a form of harassment, or targeting content which is justifiably and legally fair-use.

Hosting services don’t even try to validate these claims. You assume OP is asking for piracy reasons; we have no way of knowing, but I’m always going to side with the content providers against the gross abuse of DCMA by media corporations.
