the top 3 voters of each month should be given some reward. Here is an example: 1. $10 gift card for the server shop 2. 3 donor keys 3. 1 donor key It would encourage more people to vote consistently and also gain recognition to the server due to these extra votes!
Gift cards seem pretty cool; however, seems too frequent of a reward to give out. I like this suggestion overall and if we can find a way to implement this automatically, it'll sure be a thing in the near future.
