The accused are suspected of:
Slow-playing games where he is behind
My game - Game 17945043
Another game he was doing same thing - Game 17946707
From looking at those 2 games he has not missed a turn yet, we all have 24 hours to play our turn, I should know as I am one of the worst offenders for red zone turn playing.
If he was deliberately holding you hostage that would be a different story, but at this stage from what I can see all is within the rules.
I don't think this will get much traction with the C&A mods.
