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.
Yup, I had the same thing happen to me once a while ago. It is normal and really comes down to the luck of the draw considering how much repetition there is of the same work unit in order to ensure integrity of the results. I can't remember, but it may have been not long after folding2 was put together last summer.
