Then what am I doing wrong? I don't get points for votes.
I don't think you get points for voting anymore, but you do get them for being the month's top voter.
If you want to get points, the best method is to contribute on the forums in a meaningful way. People have been stingy with their votes lately though.\
EDIT: To clarify, people have been stingy with their votes on forum posts (not server voting) and that is relevant, because the points you get from forum contribution is derivative of the votes you get on your posts.
