This is exactly what the thread was missing, some words of wisdom combined with some straight-talking that does not care about what others might think. Not that long ago one account in particular that should never have been considered for merit source became merit source. Though slightly off-topic, I think the problem you posted about branches out further (and theymos should never have allowed it to happen).
I understand what you say and I agree, but how do you do it?
if you put rules and boundaries we become a police state, so how can we prevent these people from cheating?
easy we use a passive method i.e. we don't give him credit
I personally put people on the ignore list so I remember that I don't have to give them credit.
