I have never rented a VPS that shared bandwidth before mine have always came with a dedicated line, usually 100 mbit/s. In all honesty I can't think of a single server company that really wants to allow someone store illegal copyright material on their servers. Just because a seedbox company or server reseller says you can torrent on them 9/10 times the actually server company that host the servers forbid it in their TOS.

Now if I am just causally downloading a few torrents then yea a VPS is what I would go for. However if I am a dedicated uploader or very heavy downloader then a dedicated server is what I would go for.
