It has already been done [1], the issue is that Bitcoin is not really made for large files storage, so you'd store hashes to a torrent as you suggested or you'd split parts of the illegal content that then would require some other protocol be recomposed... Historically that has not been enough to cause legal trouble for network participants, another reason is that this data can also be deleted from your own node once you are made aware of it. It's been an anti-Bitcoin talking point for many years, nobody really cares about it. [1] https://blockchain.comsys.rwth-aachen.de/ https://blockchain.comsys.rwth-aachen.de/
