Every user has a maximum of 40 votes in a day, but I can only vote 36 times in a day. It might be some sort of bug, but it could also be a punishment of some sort. I don't know what made this happen or why it happened, but an idea or guess would be much appreciated.
And it's not just today...
It's every day. Maybe it's how frequently I (up)vote questions and answers; I'm sort of naive.
Is this normal?
