Due to insufficient proof of the user's SteamID, I am unable to accept this report.
As Raeker has already said, in order to get sufficient evidence of a user's SteamID, there are a couple of things you can do. If your evidence is a video, then within this video you can show yourself copying the SteamID from the menu within the TAB menu and show yourself pasting that into the chat, or alternatively (the preferred method which I would recommend), you can simply type 'status' into console and then take a screenshot of what is displayed there, which we can also deem to be sufficient proof.
