The ability to moderate sounds like a good idea in theory to the extent that a group or community might be the private property of a given admin. That is assuming a Steem community were to be private property and not public property or some kind of hybrid. So, it is a debate between censorship and customization. Some people might say it is censorship. And some people might say it is customization. I see both sides of the debate. I like customization to the extent that it your thing you are customizing. A big problem can be found to the extent that a thing might be public and not private.
