One way this can backfire: if you have no reputation and are nobody, and get banned and publically ridiculed, this is now a badge of honor you can take to wealthy and deluded people convinced of the AI future, to say 'look, I have been shot at! I'm a true believer!'

And then maybe they will give you money.

Only if there's a wealthy political group that hates the thing you just got ridiculed by. When you get expelled from a climate conference you can become a right-wing figurehead, but when you get expelled from the cURL vulnerability program, nobody cares.
