Pimp I know how you can be level 30 forever! first off this may or may not work.
WARNING: any other users besides Pimp, DO NOT ATTEMPT, that means you too HumanTarget.
Somehow trick the system into thinking that every time you vote on 5 entries the day resets for you, and only you but it does not effect your experience. I am ASS-U-MEing (I know it is spelled wrong read it.) that you vote on approximately 20-25 entries per day so in a sense it would make it look like and think that you were voting on 5 different days so in one day your exp could jump from 21,106 to 21,156. That would make you unreachable. You could miss four deposits and still be Level 30!
