No idea, but Nancy is definitily aware that most people would love to watch a B/G video featuring a man that it is not her husband or even a swapping video with another couple. She's fully aware of that and posts like the one she deleted are certainly a way to attract attention to her content, for sure.
As for the posts featuring "feel sorry for me" as you said, for the past two years she has been posting stories that implies things about her mental health, such as the fact that she was suffering some of sort of "existencial crisis", that the war in her country made her became a sad and angered person, especially because she suffered some losses because of that (like the death of one of her photographers, who died on the frontline and she posted a story crying about that), the death of her father, who passed away of natural causes, and, definitily, the death of her beloved dog, who definitily affected her immensely.
