Ok so the Steam ID is wrong in your post, as Rezel pointed out...

I watched the demo of Graydon and I don't see anything that does't say "experienced player". I see him shooting all of the points that people hide behind. Unless you have specific tick marks then I don't see anything conclusive in this demo.

Also, the guy from the other ban thread has a separate Steam ID, so I don't know if they're correlated or not.

There is also no poll..

and no ban was made..so I would say to gather better evidence and see if it flies.
