https tracker and alternate tracker port / Which site has that?

The only way I can seed without getting my packets shaped is to used those two options (available on sct) and with forced encryption...

Is there any other trackers with this option?

Proxy

Use alternate tracker port
Check this if you are having trouble with a transparent proxy
server that is causing problems with your torrent client.

SSL Tracker

Use SSL tracker port
Please only check this if you are having trouble with your isp blocking
bittorrent tracker connections or if you are very paranoid :P
Note: Only a few BT programs support SSL Trackers (uttorrent, azureus, etc)

so is sct the only one?
