The idea of clan activity check sounds good on paper, but it absolutely fails in this scenario because of how Toribash clans are operated.

Most official clan members aren't interested in playing the game or using the clan forum, they have other means of communicating (e.g. discord), so it becomes a chore to play the game in order to keep the clan board.

Whoever implemented these checks clearly just did it just for the sake of doing something and didn't think it through. Or maybe some people just like to watch the world burn, seeing as pretty much everyone is outraged about it yet most staff defended this idea until recently.
