I'm creating a new, Harry Potter-themed Community - anybody interested in helping to moderating it?
My current instance, diagonlemmy.social has no images, which is not great. So I'm thinking about creating an instance with a Harry Potter meme community.
Or, if you really want to start your own community, then by all means do it. Just know that it's a lot of work to get a new one off the ground and build a critical mass of active users.
OP is admin of https://diagonlemmy.social - if you look there directly (rather than at your instance's copy of 'leaky cauldron') they seem to have an images problem - anything that should have copied locally is broken. I'm not sure that the same person creating a new instance (which is what they seem to be saying) would be the solution tbh.
This seems like an addressable issue. Most HP communities these days usually have a "We condemn JKR's transphobia" note pinned somewhere. Authors are not synonymous with their published works, and I think most people understand that.
