It seems that you can vote between 5-10 times a day which doesn't seem like a whole lot. What if your donator status determines the number of times you can vote daily, plus wouldn't it be good for the sever to overall get more votes?
For example regular users get 5 votes max a day, donator status 8 times a day, super gets 12 a day, extreme 15 a day and legendary 25 votes max a day. Would provide a better way for players to make some money and would help the server get more votes which draws more new player.
