Reapplication - Coya

So actually I've already applied by E-Mail, 1-2 Months ago. But have logged in very rarely, and now for like 1-2 weeks when I try to log in i get the message "Kicked by admin".
I don't know what the problem is since i didnt do anything on the server than looking at the buildings. I would quite like to be able to join the Server again
Thanks

My Charactername is Coya

Edit: Of course I'd like to build some stuff too, I've invested a good 40-50 hours in my SP world. But I am getting kind of the feeling that its pretty pointless building big stuff, since nobody is there to look at it.

Hey Coya,

The server is set to automatically kick anyone who is not on the white list. This prevents server overload and griefing.

I've added the name Coya to the white list. Our server address is sc33.servercraft.co:8831

Welcome aboard!
