Auto abandon banned for just stopping queuing up in matchmaking?

[Kingly]

Got banned at 4:11 am for what looks like no reason? I started and left matchmaking last night and wonder if that did something? I'd see no reason to be reported for Innappropiate behavior because I don't use vc/text chat like whatsoever.
Last 5 match ids:
45863143
45854850
45852503
45847380
45844738

Same deal, last match (id: 45923643) got me banned for not charging the game in time
