dont quit but i get banned?

So as the title says, Im just playing for some fun listening to a podcast and i havnt quit a single game all day and suddenly im banned, and i cant even see why either.

What gives exactly? this isnt the first time im banned for no reason after hours of playing and no quits or betrayals or anything. they usually just last like 5 minutes and its usually i finish a match and suddenly my thing says im banned.

the other day when i signed on to play it just said i was banned for some reason even though i hadnt even turned the system on for a few days. i just turned it back off and didnt deal with it then.
