When my ratio goes low, I go on seed binges. I purchase an EC2 instance on Amazon's AWS through an anonymous company, download a bunch of highly desirable torrents and then seed the hell out of them. My ratio is getting pretty close to parity, so it's time to do this again.

Instead of spending the money to do this with Amazon through an anonymous provider, I want to try and use a proxy service like BTGuard. But I'm not sure this makes me anonymous while seeding. I understand that my downloading will be anonymous, but will my seeding? How does an incoming connection reach me if I am behind a SOCKS proxy? Does BTGuard somehow forward packets destined for their IP address to my connection? I also know that I can test my downloading IP address, but is there a way to test my upload IP?

Their help page is not working at the moment, so I thought I'd ask here. I'm a programmer, not an IT guy, so I'd rather hear an answer from someone who knows than just make assumptions.

Thanks!
