I know an unpopular server, but I don't own it, its ip is Crunchbone.com I've really been wanting more people to join it, but all you can be is a member, you must earn trust to get the honor of an admin. They have a few pvp minigames, but it also has spleef. Just go on sometimes you might find me on it. (catch is its a 1.7.2 server!)
No bad words on it!
