I disagree. You could just join one of the player servers that has survival already. Also, not many players played it and people didn't really like it. CubedCraft had a good reason to remove it, especially because there's like 2 million player servers with survival.
I totally agree with @erik6147 on this, especially when its very easy to make your own survival server.
All you need to do is get a world and maybe a few plugins and bingo. Survival made
Most of the things are with Plugins and skripts and all the other Developer stuff other than Staff / moderation things
And Denied... I am going to try to write another soon, but I am going to spend more time on it. I got denied because it felt a little rushed and I wrote it so it would seem like I'd be not so chill.
Good luck on your application
