No worries, the votes get posted on various sites that basically function as advertisements. Here are a few popular examples:
Basically, a vote plugin will allow players to do /vote in game (or on our site if we add that module) and get a series of links (similar to the above listed) that they can go to, vote - which tallys for the server and ranks accordingly, and then earn some reward. The system is automated and common rewards are diamonds, money, and sometimes kits. It's fairly easy to setup, I've used votifier in the past and you can execute command lines on vote so the possibilities are pretty endless.
The reason a server owner would to this is to help increase awareness, advertise, and give a little "thank you" to players who help spread the word. There is a limit of 1 vote per site, per 24 hours.
If this is a route you'd like to take with the survival server, I'd be happy to crank out some banners for sites. Just let me know if there are others than the above and I'll get them formatted accordingly. I'd be happy to chat more about it too if you want when we're online together.
