You can edit MediaWiki:Chat-welcome-message to notify users of the 5 edit count rule. As it appears to every user on entry (unless they've gone to rather extraordinary lengths to remove it) there's very little excuse not to be aware of the rule.

There is no current method to automatically kick or deny access to users base on any criteria that I've seen in action. I know Bleach wiki runs a bot to notify everyone about an editcount requirement on entry, if there was a way to block them automatically they'd probably have figured something out by now.
