Banning relays would also be a like a game of whack a mole and largely ineffective - you could just pop a new DNS in front of it, or route it through a local network. It would be almost impossible to keep up with and I don’t know why clients would be incentivized to do so. I think what is more likely to happen is that people flock around relays with potentially different ethos or community goals, and users participate in the ones that align with their goals. If you have something extreme to say, are you guaranteed everyone will hear it? No, but you should still be able to get it out to those that want to. And I think people are just as entitled about what they don’t see/hear on these platforms as what they do. The goal should be user empowerment to configure and tune in to whatever it is they are interested in, and tune out to things that they aren’t.
