Any recommendations for generic rules?

I’ve been creating communities that I noticed were missing, but didn’t add any rules or anything. Just focused on content creation.

Edit: I settled on this:

Rules:

1. No bigotry: Including racism, sexism, homophobia, transphobia, or xenophobia. Code of Conduct.
2. Be respectful. Everyone should feel welcome here.
3. No NSFW content.
4. No Ads / Spamming.
5. Be thoughtful and helpful: even with ‘stupid’ questions. The world won’t be made better or worse by snarky comments schooling naive newcomers on Lemmy.

Feel free to use it.
