User blog:Thelennylegoshow/Vandalism: need help

Anyone know how to ban these wiki contributors who keeps vandalizing the monster truck wiki? They keep vandalizing it on a nearly regular basis. (http://monstertruck.wikia.com/wiki/Monster_Trucks_Wiki)

Users who need to be blocked http://monstertruck.wikia.com/wiki/Special:Contributions/209.2.60.78 http://monstertruck.wikia.com/wiki/Special:Contributions/205.196.66.1

This wiki doesn't have any admins that we are aware of, so we are having trouble banning them. If anyone could help, it would be appreciated.
