I suppose that makes sense. I feel like that might lead to a lot of unnecessary reports. Like if one instance doesn’t allow right-wing or NSFW content but federates with one that does. If a user reports it then the other community/instance is going to hear about it. It’s easy to ignore but legitimate reports might get swept up with them.
Are you trying to import content? I don’t think there’s a way to do that. There might be a way to mass download content posted by a user but I feel like that’s probably it. I don’t even know if there is a tool for doing what I mentioned for Lemmy.
