Banned for no reason on invex retake CSGO

[Strang3]

In-game name: Animal

I was just playing retake and admin : S0N1C just banned me for on reason after winning a round as a terriorst.

I play Invex retake all the time and this time he just bans me for no reason.

Now he blocks me on steam, wtf is happening? Admin loses bans you??
