I remembered someone said that every user has the limitation of voting to another user. Once he/she vote up/down the same user's post more than a certain limit, the excess votes will not bring any reputation to the user. The rule will prevent anyone gaming reputation system.
But I voted up 10 times to a user (Moderator) today, I noticed that his reputation increased by 50 points.
I am confused, how many votes can be given to a certain user in 1 day?
