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.
Used Acoustipack in two cases and love it. Will use it on any other cases I buy. A case fully outfitted is quite a bite heavier. Zero experience with Damptek. But Acoustipack is about 50% thicker. My advice is whichever you choose, don't skip, buy more than you think you will need.
