I guess everyone that is interested in a serious conversation about Nimiq stopped using BitcoinTalk and moved over to their other communication channels (Telegram, Discord). The trolls had too much room and apparently forum moderators didn't consider that excessive trolling a problem (only some posts were deleted and the users not banned).
I also can understand that the Nimiq Team doesn't want to go self-moderated.
  1) It will support the trolls claim of being censored,
  2) looking at how aggressive these trolls are, moderating a thread could become a full-time job without the forum moderators banning the trolls
and should forum moderators decide to ban the trolls, the thread would work fine without being self-moderated again....

IMHO, forum moderation/administration team failed to see the need to act here and thus rendered the thread and its forum unusable for serious conversation, which (again IMO) is exactly what they should aim for, to allow the forum to be used for serious conversation without unnecessary distraction.
