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'm going to take a wild guess and suggest that spambots used post deletions for nefarious reasons to get around the requirements to post in the For Sale/Trade forum.
It goes way back when the forum first started and all of the bells and whistles were all operational. As they were abused, they were taken offline. We would have people post a thread and get an argument started and then delete the thread and start another one. It got to epidemic proportions so it was removed. It made moderating the forums extremely difficult.
