This is Brian Jacobson from Valve. There have been reports of scammers trying to impersonate me on Discord. It's not me, and no one from Valve will ever contact you over Discord; and I will never contact you personally ever over any service. We don't have any ability to take down scammer Discord accounts; please report any such scammers to Discord.
