I found this video, talking about some Minecraft EULA announcements.
Not saying that the server particularly goes against this. But you may want to take a look anyway.
I saw this! Hopefully we (Foxcraft) will be fine, but like the owner of G**Pv* said, we can just join on 1.9.2 and below, who plays on 1.9 anyway. It's only fun for survival and creative, nothing PVP based.
Note- I censored "G**Pv*" so I didn't have any issues with supposed "Advertising"!
