It is the Andrew Anglin treatment. They pretend to take everything he says 100% literally when probably 90% of it is exaggeration for comedic effect. Then they use their literal interpretation as a pretext for a "encouraging hateful conduct" or "offensive" or some other completely arbitrary rules violation that would never be applied except to dissidents.

My hypothesis is ADL has someone paid to monitor Nick's telegram and whenever it looks like he is opening on a new platform they make a call.
