But what exactly is RatioMaster? How does it interact with YGGTorrent’s sophisticated anti-cheat scripts? And most importantly, can you use it without getting banned?

: It operates independently of your actual torrent client, meaning you don't even need to have the files you are "seeding".

YGG rewards "old torrents" with bonus points (depending on the version of the site). Leave 20 small torrents (100 MB each) seeding for 6 months. Convert the bonus points into upload credit. No cheating required.
