Some of our GM team's day-to-day tasks include investigating reports about Code Of Conduct and EULA violations - most commonly harrassment reports, flooding, spamming, or other types of inappropriate behaviour in public chatrooms inside or outside of the game.
Our team thoroughly investigates each of these reports and takes actions where appropriate. Please understand that we can not communicate about what kind of actions we take against a particular user, if any - That's confidential between us (the Company) and the user.
But rest assured that all reports we receive are taken serious and will be investigated by a member of our GM team as soon as possible.
As for the possible results of an investigation - All reports are dealt with on a case-by-case basis, which is why polls like this one are generally unsuitable to reflect what kind of decisions we make when coming across a violation. It always depends on various factors, such as the type and severeness of a specific violation, whether or not a user has previously been warned for violating the rules, etc.
Generally speaking, I would not rely on what you may have heard from other fellow players about what kind of penalty they claim to have received or not.

If you have any further questions regarding this topic, I'll be glad to answer to them. While we are of course forced to remain discreet to some level here, we have absolutely no problem with taking the time to explain our policies and procedures.
