1), You can see in your torrent program what you've downloaded...? or at the very least in your files. I wouldn't bank on the inactive/active tabs though as mine says 1047....and i've seeded way more torrents then that, it seems to always reset to 1,000 every so often.
2) you can use your servers proxy to make another account easily, i don't see the point though...ratio doesn't matter, just upload loads
3)o just guest download like everyone else and change the tracker information after its done, everyone else seems to do it...don't see the point in that either personally.
