dunno, its kinda stupid sometimes, either someone says something funny or helpful, then i rep them, or they're a friend who i rep whenever i can, or i dont, or if they're a particular asshole then i neg them.
i've only ever asked for rep when im a few points from my next box, i've done it about 3 times, but writing on ppls walls "rep me" is kinda gay.
tho that particular person im sorta friends with, so its okay
