Maybe communities could set, voluntarily, some sort of tags that can be subscribed to or used for search.
With that idea, cat memes, cat owners, cat pictures, etc. could all be viewed together if they include a #cat tag, regrouping them, but without a hierarchy.

Their flag is extra wide

I definitely agree on respecting how other instances moderate themselves and I'm happy I can choose what I interact with. It's just so new and it's hard to find out what the vibes are. I hope I chose well with this one.

It definitely is an interesting and there might be some merit to it. I'm just worried. Let's say I post in lemmygrad for any reason and then comment something unrelated and neutral on a beehaw post. Will I be silenced because of that first instance's bad reputation? Maybe I'm thinking too much.

Yeah, not opposite politically. You described it better.

nonono, It's not that. I haven't lurked there for very long, but it seemed that they were trigger-happy on bans from what I gathered. I don't have examples at the moment and the modlog feature doesn't seem to work well..

I've had some thoughts pop up when reading the post and your reply.
So beehaw said this may be temporary... But I can't help to wonder what that means.
Let's say lemmy.world closes registrations and beehaw refederates. Are they going to be flooded with all the posts that happened while we were defederated?
The amount of stuff suddenly appearing everywhere would be unmoderatable, and if I'm not wrong, it also kind of makes defederation permanent if it goes on for too long. Who would want to refederate instances and tsunami their own with things they don't know about?
