Why is it that direct downloads are considered safer than torrents (anti-piracy wise). I know some torrents can be tracked and your ip can be logged if a ISP or watchdog group like the ESA is monitoring the torrent.

But why isn't that so for direct download sites like megaupload what has to happen in order for your ISP to monitor those sites and is it even possible for a 3rd party watchdog group to do so? Because it feels like a direct download site would be x100 times safer than torrenting because from what I see most copyright infringement letters come from watchdog groups that your isp forwards to you.

I am just wondering this out of curiosity, if you have any knowledge as to why or just some crack pot theory please feel free to add.
