Voting and donation helps the server in different ways. Voting helps the server climb the leaderboard whilst donation helps the server get funded to renew the custom domain and hosting for us to actually get to play on our beloved SkaiaCraft server so yeah, they shouldn't be able to get bought for voting points. Cueballcraft OP armor is called "Donor Armor" for a reason; the term donor means "something achieved after donating to a certain foundation or anything you'd want to call."
Also, if Donor was able to get bought via voting points then the server might lose one of its major source of funding as cueballcraft is one of the largest server holding 60% of the server population and due to the murders now a days, players are more tempted to buy donor to have slight advantage in PvP.
Can't believe I wasted my time typing this ****.
PS. CueballCraft is the best semi-vanilla server around! :3
