I don't understand why you care how mucked up the server list is. There's nothing forcing you to be offended by stupid people doing stupid things. Just don't join the server, skip over it on the server list, and join a server you're interested in. When I'm looking for a nice freebuild to jump around in, I don't complain about all the TDMs I don't like clogging up the server list. If anything variance is a beneficial thing to Blockland, it provides a wider platform of things people enjoy doing on the game, and maybe some of those children will grow up into real Blockland users who don't visit family RPs.
