Open #Fediverse though / question.

On a thread about someone being brigaded here (and being able to use the tools available to shut out the bad actors and several of their servers, working as intended), it was mentioned by someone that it's relatively straightforward for bad actors who've had their servers banned to create new servers and start again.

To my knowledge, there is nothing really blocking that scenario. What are the options? Because the risk is that if it's as easy to set up a bad actor in Fedi as it is in, say, the email server ecosystem, then the long-term trend of this experiment is we end up where we are with email: a few big players with a heavy first-mover advantage because new nodes are assumed default-hostile, and it becomes nearly impossible to set up one's own independent node and have one's messages seen by people on the established servers.
