it makes the games much more enjoyable to have hackers banned on the spot rather then after 5 hrs when he's gotten bored of hacking, which is usually the case since things sit around forever in the report abuse section
1) Even though we as mods are able to ban people, we still need to provide proof, so we can't just ban on the spot. (On the spot, I mean by see a funny movement and banned straight away, with proof is like 15sec-30secs of getting solid proof)
2) Its better for the report abuse thread/topic to be sitting there wait for a mod than not posting at all. That just lets the hacker out for longer.
If you saw a crime happening around near you, would you report it to the police or think "Ah the police will catch him later". No, you would still report it to the police, and its the same with hackers, you report it asap, otherwise you are just helping the hacker play for longer.
I'm not flaming, just saying things.
