We have tried voting. It didn't work out. We barely got any players due to voting itself. The only reason the server you mentioned (you shouldn't really mention server names though) has a lot of players is because the server runs ads on the vote-sites. You vote on another server and you see that server's ad almost every day, then something happens to the server you're on atm and boom, the first thing you think of is the server that ran the ad.
We currently have one or two ads running, I'm not entirely sure about where, but they have brought us some players, unlike voting. Voting didn't get us players, thomy didn't want us to give the site free clicks without getting something in return. So that's why we don't have voting.
Want players? Invite friends & make quality youtube content, that's about all you can do.
