Since you are already on Mastodon, I would start by checking out the instances of people you have interacted with. Many topic-instances are still pretty general-purpose. Decentralize yourself! Join two or three instances. Subscribe to different topics on each. See what sticks.
On a small instance, the local feed is much more important. Local users have a larger influence on what you discover. So, check the local feed first. It may be a bit boring but should be free of spam. Check the external feed. It should not be too tacky, and have a CW where you want one. Check the moderation policy. If you want to commit to only one small instance, find out who pays the hosting and maybe donate.






Reminds me of the text-based role-playing heavy MUDs, where the players did their “pose” (a short paragraph describing what their character does) and you wait for 5 minutes while the other player(s) describe their move in return, often also adding a bit environment description. Some of the better player’s logfiles were basically prose you could almost publish. (Example: SpheresMUX)
Also, you got to like the name they came up with: it’s a MUSH (multi-user shared hullicination).
