https://www.minestatus.net appears to not be working right now (or any more). The last couple of times I have voted on it, and made sure to enter my player name as usual, it says the voting was successful but I never get an extra vote added to my monthly total, nor any in-game voting point. But yet, if I try to vote again, it says I need to wait another 12 hours. :-\ The other five voting sites seem fine so far. I believe ezeiger92 mentioned this happening to him once lately too, so this isn't just me. Thanks in advance for whatever attention the admins may pay to this.
minestatus.net does seem to be buggy at the moment. We are looking into it. minecraftservers.net also seems to be playing up. It goes to an error page after voting. I have contacted their support page to try and get it fixed.
