Aaaand there we go again.

What Ron97 says is theoretically possible, but so far I have seen absolutely zero evidence of that - though if I missed it, feel free to elaborate. In fact, from what I can see in the admin panel most reputation ratings make sense, more or less - except of a lot of the ones Dermo or Speeza did, and they are no longer able to rate posts.

So, let me repeat, no theorycrafting about how the reputation feature may or may not mean the inevitable doom of these forums without something concrete to back up your claims.
