Do you think if a girl changes her profile pic to a bikini pic, she's seeking at

I thonk it means she wants to raise money for charity

Yes, typically it's fishing for positive attention.

I miss being young enough to have fb friends regularly post bikini pics.

Yes

They aren't Facebook friends that I was looking at. I was just searching friends of friends or people I recognized and got side tracked. I do have several young Facebook friends though. In the cases of the girls in bikinis lately, I do not know any of them. I'm wondering how young I look if they clicked on my profile though. probably wondering who am I? or why did I pop up on their suggested friends list. I did the same thing to some girls who were friends of someone else only a week or two after first clicking on them not remembering who they were.

When they change from a bikini to a picture of just the face, it means they're in a relationship.
