Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.
Once you have enabled 2FA, your account will be updated soon to show a badge, letting other members know that you use 2FA to protect your account. This should be beneficial for everyone that uses FSFT.
I tried ordering from cddiski.ru but I'm pretty sure it didn't go through. I can't read russian but I entered all my info and it took me to a screen where it looked like it had been completed, but apparently I got an email saying its not complete.
I've used cjs-cdkeys and have never had problems with them. Same with offgamers(bought some wow and sc2 stuff from them). One you don't have listed up there but is also legit is onlinekeystore.com
