My first response would be to create a site policy. State what's not allowed and have consequences. Try talking to the people responsible and try to reason with them. If they don't change their behavior it shows they don't care so this would be the time to issue blocks (nothing very long, just so they get the idea). If it continues when they get back repeat the process with a longer block.

Keep at it. Every wiki gets vandalized at some point and it can be frustrating.
