Simple pre-moderation request, for example map is 40x40 hex, moderators/game masters can broke 40x40 grid to 5x5 grids or 10x10 and moderate messaging by read chat and left click (prove) right click (dissaprove) or something like this.
I think it can make game more soft and clean.
Also moderation not just in town but simple encounters and map ( for exapmle TB trap or Tent follower or simple meeting at map in encounter can end by violent language ).
System like this or nearby this was used in MMORPG Lego Universe, which one is, sadly, closed now.
Reason is players often or not so often insult each other or talking nonsence and spam.
