The web site is completely out of our control and is operated by another party and tallies up its own vote counts based on how many times you go to that site and vote successfully. Our plugin tracks votes when you /vclaim them since we have to have some sort of action take place to tell the server to tally up another vote for you (the server cannot just tie into the web site on its own). That's where that total comes from. If you have less votes in game than you do on the web site it means you forgot to /vclaim
