There are titles for having -20.000 karma, but there are no titles for having more than 2.500 karma. maybe some more of those titles could be added.
Other possible new titles could be given for people who reached a spot on the leaderboard.
Maybe a title for reaching top 100, 50, 25, 10, 5 , 3 & top 1 for each of the leaderboards. and maybe some titles for reacing multiple leaderboards aswell
