I do use Bit Torrent. If you play World of Warcraft, as I have been doing since 2005, you have no choice as their updating and patching system uses the bit torrent protocols to download. You get part of the files from their servers and part from other players who have already downloaded it. I also use uTorrent on rare occasions when it's the best or only way to get something I want. I have encountered bad files but my AV of choice at the time has always detected the bad parts. Avast is particularly effective for bit torrent protection. I did register a long time ago for a Facebook account but I haven't used it in a few years.
