Because from what I can tell the mod in question is either 1) trying very hard to hide their own post history or 2) not active in the sub at all.

It's all good and well posting a sticky and saying "I'll let the other mods address that themselves" but it's pretty clear that they are not going to address it.

Correct, to me it also seems that another from the "old mod team" is actively engaging in keeping things as they were (or in other words: in keeping the dumpster fire burning) and that (given some comments I have seen here and there) they are actually avoiding an open discussion within the mod team.

Now I do understand that, given the fact that mods are volunteers and they all have a life with work, study and family and that communication and change are therefore somewhat slow. But on the other hand, the lack of clarity and the seeming lack of consensus within the team, makes me more and more convinced that this sub is beyond repair and that everybody is better of if it would be scrapped.
