Last week my 20+ year old account was suspended for "Child Sexual Exploitation", no reference as to what this was, I would never and have never posted such things. I do not post pictures of my grandkids at all so this isn't a mistake by Meta. I appealed and my account was disabled. I have no means of contacting Meta, no ability to defend such an accusation. As a 68 yo Grandmother, this hit me pretty hard but there is no recourse with AI.
