So I was just in a game on Goldrush, playing red engy gunslinger/wrangler. A new round started, and there were a few other engies, so I was concentrating on upgrading their buildings. Suddenly, I see a thing come up saying my name and Yes or No. I say something to the effect of, "wut?" and then get disconnected. My internet isn't the greatest, so I am used to the occasional lag or disconnect. I reconnect and keep playing, upgrading teammates buildings during setup. I mention in the chat that I got dropped, and notice people yelling at me. Then another thing comes up with my name and Yes or No, and I ask what it means, and someone says "it means to gtfo." I get dropped again, and when I try to reconnect, it fails. So I go look in the console and it says I'm banned.
So I just came here to see if I could find more information. I tried following the directions on the sticky in here about appealing in SourceBans, but the link is dead, hence why I'm posting. My steam ID is STEAM_0:1:308246 if that helps. I know there's a bit of hate for mini-sentries out there, but this seems a little extreme, doesn't it?
