On gear and items created by person displays the name of the person who created said item. But yet some items will only say "Obtaining Signature".

How do I get my name off items I created? I am being harassed in game by an person using my in-game name and at the end STANK, SALTY and the GMs have done nothing to stop this harassment.

They post one item below by 1 gil and above my gear listed on the market board by 1 gil with those type of retainer's names.
