The Zoids wiki avoids this by having a rules page. I'm not sure what problems there are on the thundercats wiki, but the way we deal with it in Zoids is to have an unambigious rules article on the main page. It means anyone wanting to argue the rules is restricted to arguing on the rules talk page itself. Any edits outside that page (which conflit with the rules) can be considered vandalism, and pointing the user to bring it up on the rules page works.

This isn't punishment, since the rules can change, if they have a valid point that hasn't been raised, then the rules can be updated.

Otherwise, disclaimers don't hurt either. Several pages on the Zoids wiki state "this article may be subject to spontaneous change, as most Zoids: Genesis material has been sourced from subjective, unofficial, and potentially unreliable, translations of what is currently a Japanese-only anime. As such, edits should place preference on consistency, rather than correctness, until an official translation becomes available."

Consistency over correctness, on contended articles massively improved the quality of the Zoids wiki. Not sure if it would help on the thundercats wiki.
