Bluesky, like Mastodon, is built on an open network on open source code. Run your own data server and moderation services that cater to your needs. Many are already doing it: Northsky, Eurosky, Blacksky, etc. If you want to live in a safe space isolated from the mainnet and its allegedly toxic users, you can do that too: Roundabout is built on ATProto but run on its own network, also Truth Social and Threads are forked versions of Mastodon but federated with nobody (Threads used to have opt-in Mastodon federation before Facebook decided they no longer want users to be able to do that).
