whats a good site to get proxies for downloading torrents, so that you don't get notices from your ISP. got an email a few days ago, saying that a movie company contacted them because i downloaded there movie illegally, and that i should stop doing so.

A VPN would be preferable for downloading torrents.

VPN is secure than proxies.

will download speeds suffer with the use of a vpn?

VPN is the correct answer.
