Sometimes you're going to get dragged into a battle. It happens, that is not an excuse to be a jerk to the person - especially considering how many new people we have that are still learning the mechanics. We do not tolerate people being jerks.
Let's do a little rules reminder (http://forum.game-labs.net/index.php?/topic/2346-forum-and-sea-trials-rules/) - and yes, these rules also apply in game:
Looking at the chat screens above, I believe that all of the parties were violating the rules. The person reporting it was making comments, the people being reported were making comments, I see culpability on all hands.
If you don't like the way someone is speaking to you, if they're breaking the rules, right click their name on a rude statement, and hit "Report". Follow that up with right clicking their name and selecting "Ignore". Done. If you start going back and forth with them, it A: Encourages them, and B: means you're being almost as bad as they are. Your case that you are being abused or bullied starts to become rather thin when you're giving as good as you're getting.
Stop responding to them, ignore them, and move on. Case dismissed, unless everyone involved would like to risk a chat ban?
