This is really cool. Is there anyway to keep some people off my small part of the webverse?

Having read some of the comments, I'd happily use if there was a way to blast (prefarably with a Doom shotgun) some of the miscreants from appearing, but only on my site, and maybe some filters (slurs, etc) that auto-ban them that I can set. Other people could moderate as they will but I'm kind of tired of the toxic people ruining everything.
