Wow. So you are saying all those posts were shared automatically and she didn't have to stay up all night making posts? That is one big mystery solved! I never knew that was possible. Thank you!
Nope, she still had to 2-click each previous photo to get them to repost/"share" like that. So you're correct that she stayed up all night, refreshing the content on her FB for some reason. Promoting previously posted photos so they'd be at the top of her timeline, for whatever reason. Maybe to entice some guy? I've no idea.
