I got IP banned from a Minecraft server for no reason at all?

So I was playing on this server: 198.24.162.90:30212

And I was talking to everyone, having a good time, its a very small server. Then I suddenly got kicked out of the server, for no reason at all. So I tried logging back in, and it just said

Your IP address has been banned from the server! Reason: Banned by an IP

What the hell? This is my favourite server and I can't get in touch with them, so what can I do?

Added (1). Hey, so I went back on the server today, and i logged in without being banned! The server must just ahve temperary bans.

You can try using a proxy. I used it once and It worked.

Lol, try get a friend to go on the server to explain to them?
