MMG could add a monitoring symblo to all threads so members can rate the thread and the especially for HYIP's. People could be alerted quicker as to wether the deal is good or not.

Nice idea.. but I still don't think that's going to be a good way to judge. Those can still be easily manipulated.

I think that would just be inviting admin's and promotors to make multiple accounts strictly for voting purposes. This would be nearly impossible to catch, and would be very misleading.

It's an interesting idea, but I can't think of anyway to do it that isn't open to abuses.
