Punishment for unsportsmanlike conduct. Although I think a temporary ban in one game would have been enough...
That would have been the most sensible solution. What the AC decided was complete idiocy. Especially the circus with the discussion on an external resource with encrypted names, even though half the people immediately knew who they were talking about, and the other half could only guess. That is, even in the discussion of the situation, people were put in unequal conditions.
In general, in this case, the AC created a complete mess. Sorry, but things need to be called by their names.
In my opinion, in that game, a temporary ban should have been applied, and we should continue playing.
