Game rating/hype meter suggestion

I am not saying this will be easy, but Please consider:

When taking entries of votes for games, the vote should be weighted on how active a member is.  Members who have little to no posts should have very little influence as compared to normal, active members.  Maybe you can track how many posts a person reads before evaluating how much weight their vote carries.

Why am I suggesting this?  Because some of the voting may be fraudulent.  People can make a bunch of accounts and vote from each account.  Currently you only need to put in a very small number of posts then you can vote.  This is problematic.

I would be curious where some of these votes are coming from
