I don't know what you mean? The ban references "cytraladox" which I assume is someone else's key. I was playing yesterday from home, didn't do any of the things in the ban (chucklefucking, griefing, something about "buttsecks and cum" in crayon) when I tried to log in while connected at the library I got that ban message.
It seems like an IP ban because my very first time playing SS13 was a couple days ago from the library and couldn't log in to Colonial Marines, got a ban message right away talking about multi-keying. That ban seems to persist once I tried to log in from home.
I've been playing on Aurora Station from home only, but today tried to log in from the library and got the ban message. The ban is now persisting at home as well.
It's very confusing because I'm brand new to SS13 but can't seem to play on a lot of servers from what I believed was logging in from a public IP. I tried Aurora while I was home over the weekend and started figuring things out and having fun, now I seem to be banned for something someone did in 2015.
