I asked the sender to send me a video showing that PM between him and suchmoon.
He agreed on it.
That can be faked too, albeit it is far from trivial. In certain situations I reject screenshots and video and only want live footage (not that someone skilled enough couldn't fake this too) - not that this is the case here.
But like i said i would like to get suchmoons opinion on that.
If that was truly the case, you would have gone through the proper channels and not making a thread in the wrong section. Even if every single letter from that PM is correct, that would be a reputation issue not a meta issue.
