Apparently, one of the the gambling websites, CSGOBig, received this letter from Valve. Richard Lewis (CSGO analyst) says the letter is valid, we'll see though, the typos are sketchy.
EDIT: confirmed by Richard Lewis and others, it's real, RIP CSGO betting, hopefully viewership doesn't take too big of a hit.
