Just as the title says, I was idling on the server and I was randomly banned when I took a look. Please reply shortly, thanks!

What is your in-game name?

oG]Dak @Omni-Servers.com

It shouldn't be considered advertisement of a community. Omni-Servers is a server provider. Not a steam related organization.

And you feel that your in-game name should be used for advertising? In my server?

Its a Website and a company, not a community. It's unlike I am going to take any of your players away.

And it's SGC's server. Are you paying us to advertise in our servers? We don't host them as a way for you to make money off advertising.
You wanted to know why, now you know.

I don't make money off it. The serverhosting owner does. I will take my tag off and I wont have it in your server again. Just please unban me.

No.

Any reason behind this?

Yes.
