Several years ago, I assisted in tracking down and the sucessful arrest and prosecution of an Ebay scammer who was selling illegally aquired steam accounts. And as such, I had quite a lot of conversations with DougV, head of support at Valve.

At my request, and with supporting evidence, I have personally requested and had banned 4 steam_ID's and a futher 3 at a single IP address.

Valve have everyright to ban a steam_ID purely on the aspect of you not respecting other players online. They like to promote a friendly community - annoying players just cause you can does not come across as friendly!
