It was the last nick they had used before getting banned, it will be like that forever untill they join with different nick using same UID but it's impossible to happen. Anyway, we use different table for accounts & bans so his nick in ban list will still be the same even after we have transferred/deleted their accounts, The server uses aliases table to get information about players to ban them. As the admin had banned the players' UID instead of nick, the server had to find the latest information about the UID from the Aliases table( IP, UID1/UID2 & nick ) on its own & the nick it found is as showed in the ban list. So, if we change his nick in ban list only, the information about the player in ban list might be different than the aliases table & it might cause difficulties when we want to check something. So I'd prefer not to mess with these tables. The admin can re-ban one of them by entering the nick instead of UID, but it will not works with players having more than one UIDs as it will only ban the last used UID to avoid spam & wrong/unnecessary bans.
