Bruh MOBA companies straight up ban you for leaving before the match ends if you do it too much.
Not like Halo: Reach where it's "You can't access matchmaking for an hour" Nah man straight up month long ban. ***** yes you have sex but once you get back you have nothing.
Dota just puts you in low priority if you abandon more than 1 match a week I think. (Low priority is a pool of other people who got reported a bunch or abandoned multiple times , win a few games to get back to normal matchmaking) There is no banning whatsoever in dota
