A Question about the new Steam Chat

I got this message from someone who is not even my friend on Steam:

Ку, можешь тут рулeтку крутануть (link removed) Если выпадет GTA V, PUBG или CSGO я могу купить ключ у тебя. Попробуй, это займет не более 30 секунд. Переходишь --> жмешь кнопку ROLL, выпадает бесплатная игра --> забираешь ключ и пишешь мне) Ну или же, активируешь её у себя в стиме)

Google Translator:
Ku, can you spin the roulette here (link removed) If GTA V, PUBG or CSGO falls out, I can buy the key from you. Try it, it will take no more than 30 seconds. You go -> press the ROLL button, a free game falls out -> you take the key and write to me) Well, or you activate it in your incentive)

It led me to this site but there's no way I'm signing in until I know if its legit. Scam Adviser gave it a very low rating
What do you guys make of it?

UPDATE: Yes its fake, I found out in 60 seconds. Its not an intelligent scam...but that is beside the point.

I shared this because it isn't the first time I have been messaged directly by someone who is not on my friends list. I have checked the Steam's privacy settings and there is no chat / message setting. You can only disable so much without affecting Steamgifts / Steamtrades. I have taken the links down and I am sorry if you were offended...but this is real and it doesn't look like its going away.
