Experience with FB Are we Dating the Same Guy groups having real world impact?

These groups are very interesting to me for many reasons. Several women I've heard are on it are notorious for dating multiple men themselves. The nature of the groups seems to violate the TOS on all dating apps regarding sharing the information from the app.

A girl I was seeing earlier this year who already had insecurity issues and was accusing me of being a womanizer found her way to one of these groups. She said I'd been posted there with over 100 comments (!!!!) then proceeded to block me.

I figured she was just lying and looking for any excuse to end it and had found some other guy or something.

Then another woman after that that I hooked up with ghosted me and later said "she knew that all I wanted was sex," and that was why she dipped. Of course I'd said I was open to a relationship. But I said hey, a bad beat.

Then a woman I messaged on a dating app blocked me after saying 'no thanks, your pic is posted with red flags in several groups.' WTF.

Then after that, I met this really cool chick and we seemed to really hit it off. When I saw her the second time she mentioned that "yeah I didn't even look you up or anything before meeting I was really interested in seeing you." Slept together the 2nd date, planned to see her again literally 2 days later. The next day she says she's excited to see me again. Then the day of the date comes and she sends me the classic form text of "you're great, I'm not going to pursue this, yadda yadda good luck.'

So I'm wondering if the reason she suddenly ended things was because of these groups as well. As in she decided to look me up. If she just met another guy that day or the sex was bad, hey that's variance. But I'm starting to think these groups are having real world effects.
