locked forums
You've got the point:

I’ve noticed this a lot but it’s kinda odd than any post complaining about cheating gets a copy pasted response to a video about how there’s no cheating, is told to shut up, and the forum is locked. Almost like they’re trying to stop people from talking about it
I don't think anybody says there is no cheating. Only that the problem is not as bad as many people make it out to be.
And you aren't told to shut up— only that the site's owners don't want you to make accusations against other players in the forum.
