Weapon Name Tags and Descriptions
I don’t think Anet wants more things to have to monitor because of nimrods trying to be cute and name great swords or staffs things like My Big John… I’ve already seen many times people trying to skirt the rules with creative spelling for character names. Then when they get caught they try to claim innocence and that they didn’t know better. 
Now imagine the trading post getting flooded with such nonsense. It’s one of those things that could be fun but unfortunately some players would ruin it for everyone.
