If you look in the history there is is proof that you indeed did boot someone, no need to lie, even less need to bring your lie up on the forums to try and gain people's pity when it's obvious to anyone with some experience with this game that you did indeed boot said person.
i never found this bug, but could it be that when a players is auto booted (i didnt look at the game so see if that might be the case) the server would randomly atribute it to someone else? if that is the case that dint use to happen
when autoboot is doing the kick, then there is no name written, just "this player was booted after not taking his move after _ minutes"
I never had this problem myself, but i played exactly twice with people swearing they did not boot even though their nicknames were directly pointed by the game as booters.. IMHO bug is less likely than simply people lying trying not to get blamed for ruining the game but it is possible like any other bug. Only this one is a bit more "suspicious in its nature"..
