The problem with VPN servers is they get sued over the content passing through the server. Most have TOS that allow them to cut you off if you torrent illegally with them. If the DRM police trace your torrent through a VPN server, they won't find it hard to prove what is going through it even though it is encrypted, because they seeded the torrent themselves just so they could snitch you out.
If the VPN is accessing illegal content, unless the server is in Vanatu, there will be pressure or DNS blockage against anyone who doesn't play along.
TOR sounds like a good idea until you realize you don't know who is actually on the TOR with you. They can still snitch you out or poison the content.
The better way to bypass content controls is usenet. Yeah, you have to pay, but as long as a few people upload whatever is getting banned this week, there will be an way around blockages.
