what community and no i am not willing to moderate on my own

I'm not sure if there are any with that specific ruleset.
You're probably better off putting in a new community request with an instance somewhere.

!dadjokes@lemmy.world is pretty much text based.

i have a question: can i make my own community and make it that moderators only post and then post those jokes (since the jokes are long and have some lore)

Yes, there's a checkbox when you create/edit a community on Lemmy or Piefed to make it so that only moderators can post to a community. I'm not sure about Kbin/Mbin communities.

Edit: If you want to reach more users (Mastodon users), I would suggest a PieFed community since you can have every post set to have an automatic hashtag applied. Lemmy users won't see the hashtag, so it shouldn't bother them.

!jokes@lemmy.world seems mostly text based.
