Teenage girls who post bikini pictures on social media

This may not be the PERFECT fit for this topic, but it seems close - I mean what kinds of relationships are they looking for?

Teenage girls (and this can include up to 19 years old or perhaps twentysomethings, but it's mostly the ones who are 19 and younger) who post their bikini photos on social media - I'm wondering what's going through their heads leaving nothing to the imagination like that. What do they think guys on the other ends of their computers are doing? Do they not understand that once you post a picture one time on social media it's there forever for their coworkers, employers, future boyfriends and kids to see?

I'm certainly prone to making a big deal out of nothing, but when I see my own nieces doing that it disturbs me a bit.

Constructive conversation welcomed.
