im pretty sure the amount of rep points you receive is dependent on how strong the rep is of the person who repped you.
as to the exact points im not sure
This, my rep bar is pretty low.
Even though I like to think I make decent assessments in the NBA forum, and bring solid basketball insight.
But then their are others with these long ass green bars, who I don't see put much effort into their posts, and I get seriously confused how that happens, or what the purpose of the rep bar actually is ...
BTW, good and sadly forgotten PG in your avatar there.
