I'm not sure how Wikia does is exactly but I can guarantee that if an "admin" goes rogue and starts to disrupt their operation by posting redirect links, that "admin" will get a visit from the real admins and will have his/her powers removed.
Then again Elements Wiki gets so little traffic that they might not just care. Who knows, and more importantly, who cares?
Once Zanz changes the game page link and everyone starts to use the new Wiki, old one will slowly and drop in search results after which nobody is going to find it.
Bloodshadow, you could actually put a link to the new Wiki on the "old" Wiki front page right now. That would help with the transition I think. Do it and lets see what happens.
