Why can't I vote at Minestatus?

Every time I try to vote at minestatus, it says:





Can someone help? I paid for my Minecraft account, I don't get it! It happens EVERY TIME!
I feel like I have a disadvantage in the contest because I can only vote 3 times a day instead of 4.

 

are you able to play on the skyblock servers?

 

Yes sir.
Even do /seen umo

 

is your minecraft account spelled with any capital letters? it's CaSe-SENsitiVe

 

No it isn't, and I type in it as "umopapisdnpuaq" (no parenthesis)

 

C'mon I want an answer.
