It is however, true.
A moderator has used his given power to segregate targeted users from other users,
Is that not harassment? Or abuse of power?
People wonder why the forums are dying, while users aren't actually 'leaving' - it's because the forum has no content until you join the chosen elite and their PM chats.
I know this well myself, because back in Discord I created my own version of the chamber called "The Elite Chat" - eventually all of the active users and contributors stopped posting in the HB discord, thus killing it. The server is still alive now but it is nowhere near how good it was in its prime.
There is a very similar situation happening now, and until the ring leaders of these chats (AKA the mods who have admin functions in these chats - rendering them invincible) man up and say "Do we want a chat room? Or do we want a forum?" and convince others to do the same, the forums will continue on their steady decline.
