Why do women remove their profile pictures?

We’ve been no contact for a little over 6 months. I was the dumper. I had to leave after a little over a year because we weren’t working out, and it felt like a loosing game. In this duration, every now and then, she removes her profile picture and her posts on instagram. She’s never really done this in the past. And I know a few other women who do the same, and it’s almost always during times like these. I know I shouldn’t be checking her socials, especially during no contact, but I’m slowly getting over it like everyone else and it takes time. But out of curiosity, someone please answer this. Does anyone have any explanation as to why they do this? Any specific emotional state? What might be going through their head that caused them to do this?

Any personal experiences or from your friends? Responses from other women would also be appreciated.
