I heard that it's possible to block unregistered users from editing a wiki. Is this possible? I'm an admin on a wiki that has a problem with Wikia Contributors. Some can make good contributions, but most just ask spam questions, write false information, or are inappropriate. I've blocked them, but they just get a new IP address, and honestly, it gets tiring having to block them so often. I have to almost every day, because it's usually the same person asking the same question. I think the wiki would greatly benefit if this was done.
