Hello, Whilst reading the wiki today, I noticed that there is no rule for trash talking in the PvP world. It does not fall under any category of chat, or other worlds as well. We do allow some trash-talking, but just not in an offensive/rule breaking amount. If anything it could be added in the worlds section as it is a separate world category. It would be Section 7. World Specific Rules Clause 5 (Or wherever it is felt necessary) Just a little idea of what it could be.
This is something only Skylexia can handle. I'll be leaving you and your rule idea in her capable hands .
