Blocking torrent upload

Hey, can someone give me tips how can i block uploading torrents? I just want to download without seeding. Im using qbittorrent, but info for other clients may be helpfull.
So far i added rules for allow incoming and block outgoing, but it doesnt work.

You want to blocking incoming but allow outgoing. When seeding other peers will connect to your system to download files from. They would first need to establish an inbound connection first, so blocking the incoming connection will prevent other from connecting.

Now i blocked all incoming connections, but torrents are still uploading. What is wrong?

DEGREEZ basically your computer initiates the connection to other peers and begins uploading, seeding still works but slower.

Ok, is there other way to block upload completely? Even out of comodo firewall?
