Ugh. That's gross. Like, the kid part is gross.
Many years ago, on a game, we found out someone was doing something similar (not the medical part; but using photos of other peoples' kids).
It got discovered because a bunch of us from the game were hanging out (a few of us lived local-ish in SC: 3 people were roommates, I lived an hour away... a couple people had flown in to visit, so I drove down) and two guys mentioned that this girl had sent them photos of herself, flirting with them. One of them was married, had told her this, and she persisted. So, y'know, all of us young (early 20s) and drinking are like 'omg show us' and he had a link still (logged everything). Well, so did the other guy.
As soon as we see them: 'That's not the same person!'
I showed them how to reverse image search: they were photos off of modeling agency sites.
Which, OK. Whatever. We had a good laugh over it, it seemed harmless. She needed to stop trying to mack on the married dude, but OK. Fine.
...but then she began, on channels, a few weeks later, telling everyone about her kids. And sharing photos of them. And knowing about the whole fake-model-photos thing.... I reverse-image-searched those. The two photos were both of three kids, all blonde, but if you looked really close they.... looked similar but not really the same three kids.
And both went to completely different profiles on message boards.
That's when what she was doing went from 'kinda weird, but mostly harmless' into pretty skeevy.
Don't use pics of other peoples' kids, folks.
