Quote from friedtofus
Mediafire is fine, the reason uploaders don't use mediafire is because they don't have a affiliate program. Fileserve, filesonic, uploadstation, and some other site are owned by the same company so thats the reason they suddenly stopped dying. You should be fine if its just anime; the fbi is "mainly" after people who pirate music, games and movies blahblahblah.
I would assume the FBI are after people who pirate anything that an American business, company etc. hold the rights to.
So if someone owns the American publishing rights to an anime then they will come after you if you dl it. Although why bother with small fry when you can go after the people uploading it or making it possible for others to download.
