The big issue would be to get everyone to sign up for something like that though. Since things have been running for a while without any sort of checks like that, it would be difficult to switch to that system now (do you merge communities with conflicting names, do you let them change their name, do you let them delete the community, etc.). Plus there’s the whole nature of the fediverse where every instance can be customized to the creator’s needs (so one instance might want to be on that database and others might) and it just becomes too much work to get everyone on board.

Maybe I’m wrong and someone will eventually implement something like this and people will want to use it, but I very much doubt it from what I’ve seen of the fediverse so far

1. no, each server (kbin.social, fedia.io, lemmy.world, etc.) can have their own communities, since there is no centralized server that manages community names it would be impossible to track which servers already have a community with the same name
2. yes, that’s the beauty of the fediverse! this post explains how you can do that. you can also view and interact with posts from other federated social media sites such as Mastodon if you are interested in that sort of thing

From my understanding, posts are only stored on the servers they are posted on (ie. when you view a beehaw post on kbin you are actually requesting the file from beehaw’s servers). So then you would only need to contact the admins of the server the offending content is posted on.
