It is possible to report servers for violations of the Terms of Service at our support mail, but that needs to happen with clear proof. This case unfortunately doesn't look like a ToS violation. I also removed the post that namecalled, given we ask for not to do that in the stickied post.
Official servers can be seen on the "Your Worlds" button, there is a category for them.
White Tiger is restarting tomorrow, it's a concepted server, so stuff there is pretty different to the other servers.
