Smells like a macro-ban victim.
FairFight banned macro users for a reason.
Semi-Auto weapons are supposed to be just that. Semi-automatic. If you make them automatic it wouldn't be a semi-automatic. Their slight increase in damage and accuracy is to make up for that factor, and using a macro, to make a semi-auto into an automatic is against the rules for that reason.
In other words:
My aim is bad, how about we add an auto-aiming bot that also helps me see targets through walls? That way, there would be no more people crying aimbot and getting banned.
See the logic?
Oh, and i heard FairFight used to calculate a player's clickrate to determine if it's human or machine. But don't quote me on it.
