In fact I thought its already exists until I checked /gmp and found that the only name shows in the panel.So it will help the group leaders / founders to punish the player who got punished if he changed his name .. ect but in the same way I find it trivial, you can simply open the group history > search for the player name. or simply punish him "player name" without the account name so I don't know if its going to be useful or trivial so im going with Neutral GL with other votes.
4- High Priority suggestions will be stickied maximum for 21 days after the last review. If none of the developer's works on it will be set to Medium Priority again. Also, if we already have 5 High Priority suggestions, we won't add more until the current ones get handled.
