u/Eydane

It really seems to me he did that out of frustration, but i'm most concerned on how is that even possible. I obviously didn't accept his invitation. (You can barely see the pop up as it joins instantly).
Not only it auto joined but made me swap team (to join his and see "DEFEAT" even though I just won) then getting back into mine and so on about four times in a row.
After that I couldn't either invite him in a group nor as a friend to ask him what did he do and how he did that.
