Banned?

[Kaotism]

Hello everyone, my first time posting here. So heres the story.

A few days ago my friend was over at my house playing in your server, ( as usually this is mine and his favorite place to play ) and he said he got banned, I figured no big deal it was just the simple 2 hour ban we all get everyone now and then on them crazy maps like he_glass. Well I just tried to get on and play and it says I am still banned? What happened, was it more than a 2 hour ban or something?

He plays under the name "I'm Sofa King We Todd Did" but on my steam ID.
If I could get my steamID unbanned, I would be very grateful as this is my favorite server to play on. I will no longer allow him to use my ID if he truely did get me banned for a long time.

my steam ID is : STEAM_0:0:3954571

Thanks,
Kaotism
