How about a magic trick? Watch closely....
STEAM_0:0:2127804629 tadaaaa! Isn't that your ID? I managed to find it while you couldn't bother.
It appears there have been 2 more bans some months ago on the same ID and 2 IPs that do come close to your location. However, as they do not point to your town/city, I'll assume you all same about the same ISP so you just happened to have similar Steam IDs accidentally.
Anyway, you've been Unbanned. But keep in mind(this goes for everyone) you HAVE to fully fill the form properly, no matter if it's something simple or not. If you got problems finding your ID and taking ScreenShots then I advice you to re-install your game, what if (making an example) you got banned for cheating? This case would go straight to denied without an SS.
Regards.
