Deleted all my shares a while ago but wanted to leave this one here because there are people selling this stupidly simple code.
It's command based individual vote reward for Hopzone, Topzone and Network.
Commands are .votehope, .votetop and .votenet.
It is secured on both the account level and the IP level so it's as protected as it gets without adding HWID.
It can be easily converted to a NPC based one.
