Neither namedropping nor virtue signalling nor spreading misinformation is okay.

Speculating:

Restricting posting from accounts that don’t meet some adjustable criteria. Like account age, comment count, prior moderation action, average comment length (upvote quota maybe not, because not all instances use it)

Automatic hash comparison of uploaded images with database of registered illegal content.

Be advised: I recognize this person joining and speedrunning Ban% in safespaces for several months now. This is at least my 4th sighting of them. They will antagonize the userbase in record time by blatant disregard of netiquette and basic human decency. They will cite any of their vast repertoire of mental conditions or minority membership cards as justification when called out on bad behavior - whatever is convenient at the time. Conversation to them is a game that must be won at all cost and people with even slightly differing opinions are seen as enemies that need to be defeated (and also humiliated) Their strategy is generally to single out one member and harass them with wall of text posts.

Do not engage. Do not educate - dozens have tried and failed. Just identify the pattern and ban permanently, before they can do any lasting damage to your community.
