Kigen's Anti-Cheat

Hello. My name is Evan V. , and a few months back I had my account compromised because of my stupidity ( I foolishly logged into Steam on a fake steam lookalike page which was like "BLAHBLAHBLAH.steam.com", which i thought was real.) and I was unable to log on to my account for months, and I had to use a friends Steam account. After Steam support finally got me back into my account, I hadn't realized that the person had been playing on my Team Fortress, Counter Strike, and Garry's Mod (there were like 50 hours tagged onto each of them, and I only had like 40 hours of GMod beforehand, so 9X hours was a sure sign.) Recentley, I had gone into a server which had KAC, and it said I was banned, which was wierd because I have never used an illegal hacking utility in my life, and I think it might've been the owners of the phishing website trying to get me banned for unknown reasons. So anyway, I would like to get my Steam ID unbanned from KAC so I can play on the servers which use them in TF2.

Thank you for your time.

Sorry, but you KAC ban is valid for cheating.

This ban will remain permanently.

p.s., I guess the person who phished your account lives at your house then.
