You dont need to make mod lvl again. Just let vips ban haxers.

If vip banned a hacker, he need to post proofs of his cheating in the special forum section.

If he has no proofs and banned some1 - punish vip.

If proofs are not 100% - unban.

The point is that vip can lose his vip if he will abuse this power. More responsibility, but not more rights.
