After seeing _agentSmith aka can't remember the last name it was under at level 194, and reporting him, i recieved a in game message from that person telling me i was a lucky winner of a _happy2013 event, etc, etc.
I did not attack nor leave a message for this player so the only way he could have known i noticed him was through gree support. Just minutes after i had reported him did i get the message.
There's definately something really strange going on with this game??
