Torrenting copyrighted materials (especially if you are distributing) can be quite expensive in some jurisdictions and I do not believe that IPFS is treated different than regular BitTorrent.
It works well for file sharing as well. Don't know about copyrighted material though, have only shared my own files.
Why? Your ISP charges for BitTorrent traffic?
Edit: I didn't downvote you if it looks like that :)
And you have to pay the fines? That's nuts.
In the US, you are pretty much as likely to get fined for torrenting as you are to get arrested for jaywalking (although without the racial disparity).
Yes, conveniently there's a second group of lawyers that focuses on getting people out of these fines...for a fee that's not so much lower. Unfortunately it's a bit of a business model in some countries.
This is not "very" common - the ISPs don't really ban you, they just threaten you. I no longer do this, but I extensively torrented over multiple home ISPs and they would send me warnings but they would never actually do anything.
