wouldn't completely rule out the possibility that there are sickos among their Discord servers, but to insinuate that someone is grooming children with no evidence is quite questionable, regardless of your intentions. It's natural to ask for proof in the face of such a serious allegation, especially when it should be easy to obtain if several people agree that he is doing shady things and if the person in question is being transparent about those activities.
The problem now is that you brought all this to light without confirming anything, so now they know we know, which will make obtaining proof even harder unless someone who already has that evidence is willing to come forward.
