...if the reviews system is abused, there are checks in place to notice irregular patterns and take the appropriate action

I think that as long as plugin authors can rate their own plugins this "system" is completely dysfunctional.

Also users using the review system instead of support should be caught I think.

Perhaps an idea to add a report button or something like that. No doubt that such a button will be abused too, but it is very easy to "punish" abusers of that button I would think.
