Anyway, regarding Transcending, Xearsay, Beyond_transcending, and the rest of their group, I have had bad experiences with them seemingly engaging in dishonest arguments and extreme stonewalling complete unreasonability regarding DC Comics in the past, which is the same kind of double-faced behaviour that they engaged in here: Accuse any opposition of doing what they are doing, or portray themselves as victims and create lots of drama if somebody voices suspicions.
As such, I think that the best solution would likely be to give all of them permanent topic bans, and the ones who were directly involved with trying to get Deagonx banned on false premises, temporarily banned themselves for a few months in addition to that.
