You would like to have your own Mastodon instance but don't have the means?
There are (paid) services that will create and run an instance for you, you can focus on moderation (or just have an instance for yourself).
Best known is masto.host but there are more!
Just found another one by @CobaltVelvet in this toot: https://octodon.social/@CobaltVelvet/108197743288223496
Subversive.zone ist eine linke, antiautoritäre Mastodoninstanz.
