That is their statement, but this doesn't change the outcome. I cannot participate, I am not welcome in their communities. I see no reason why new communities can't be created on instances which won't defederate, even temporarally.

When it comes back, I'll still avoid the instance. I'm not going to participate where I could suddenly become unwelcome again. They've done it once, they'll do it again. As is their right, the heavy handed moderation is their stated goal, but it's also my, and other peoples, right to simply go elsewhere when we are unwelcome.

Other instances will do this too. One answer to this question of 'why create another copy community' is for this situation. When we are no longer wanted in one place, why not create another?

Thank you for the kind reply though. While I disagree with the action I'm happy they have the ability to create the site they want
