In a nutshell you can create ratio rules for example when torrent A reaches 2:1 ratio then limit upload speed to 16kb/s
When torrent B reaches 10GB of upload delete torrent and data

There are many things you can do actually, just google it

A reaches 2:1 ratio then limit upload speed to 16kb/s
hmm, that's not a bad idea I am going to try to simply just slow down torrents older, than 8 hours to 1KB/s, while I am downloading a new one

EDIT: Or maybe, I can just manually set them to a channel of no upload
