Forum:Is there a way to not allow a question to be asked?

Hi. Alright, on this wiki, an Unregistered user has been giving us hell for over three years every day, non-stop, asking the same questions at least 20 times a day. I contacted the spam wiki to help, but they said they couldn't do anything because the spammer was asking questions with totally different IPs. Somehow he's managed to change them everytime. I don't bother banning them anymore, honestly, because what's the point if they change their IP?

So, back to my point... I was wondering if there's any possible way that I can prevent a question from being asked, so that the system won't allow it to be. Because he/she only asks one question, but in different wording.

Example:


 * What is a nursing cat mother called?


 * What's a mother nursing kits called?

Is there anything I can do? It's been going on for years and the no-life won't stop. 23:38,9/27/2011 23:38, September 27, 2011 (UTC)
 * You could use the TitleBlacklist extension if it is enabled, which will allow you to block certain phrases which are commonly used. In this case, adding "What is the name of" in proper regex would prevent most of those questions from being made. 23:40, September 27, 2011 (UTC)
 * Okay, I got to it: http://warriorcats.answers.wikia.com/index.php?title=MediaWiki:TitleBlacklist&action=submit but what would I enter and where? 01:53,9/28/2011 01:53, September 28, 2011 (UTC)
 * TitleBlacklist uses regex, this page has a pretty good guide on how to use it. There are also many more on the interwebs if you search for them. 18:07, September 28, 2011 (UTC)
