Forum:Prevent IP's from removing significant amount of content from pages?

Is there any way to prevent IP addresses from removing a lot of content from pages? Recently on Backyard Monsters Wiki, it seems that IP addresses are nearly blanking pages, leaving, for example, a category. This is very annoying, so is there a way that the administrators can prevent them from removing over 1/2 of the page? Iggyvolz 19:31, April 7, 2012 (UTC)
 * Yes, there is - you'll need to contact staff and ask them to enable the "AbuseFilter" extension - then I can add a filter that will stop large removals from new or IP users --  Random Time  19:34, April 7, 2012 (UTC)
