The challenge I have with this is, mastodon servers should be able to ban other servers that are toxic, but once an app starts blocking the ability to connect to certain services because of political views it becomes a different beast IMO. Servers blocking other servers is maintaining community health. Applications blocking servers is censorship. Pirate servers would be next. Then porn. Then gun sites, etc. It may be slippery slope fallacy but it sets a dangerous precedent imo.
