Hi there,
I've got a few complains about the report system. The myth goes, that once you submit a report, you've magically banned the other person. So people began complaining that "the enemy" is reporting others and banning them from game that way.
Myths are cool, but they can also be deadly.
When someone hits the report button, all it does is send an email to us, the moderators, with the chat log and your reason for reporting this person. Absolutely nothing else happen.
Then we get the email, check it out and if it is a non-sense report, we simply ignore it. Otherwise we take action.
The deadly part is... that if you send reports constantly and there is no reason for it can get you banned yourself for trying to push innocent people out of the game.
So... yes, do report if there is a real reason for it. Sending reports without a reason most likely will just make you lose credibility in all future reports.
