Apparently dating apps have resulted in a small percentage of men being pursued by a large percentage of women. It's presumed that in many of those cases the women those men date aren't aware that the men are also dating a whole bevy of other women equally interested in them. You would think maybe women who find out and feel jilted would report the men: "Don't date him. He's a womanizer!"
Indeed.
The data seems to be a bit thin, but IMO it's very likely to be happening as you describe it.
The data I've seen mentioned online is that the number of women who report being in a relationship is much larger than the number of men. Also some quite large proportion of men report not dating, and not looking to do so.
OTOH I haven't seen anything corrected for unevenness in dating behavior, for example the natural age skew caused by hypergamy, which suggests they shouldn't be comparing XX and XY in the same age ranges.
One likely side effect of the XX/XY imbalance is that the highly popular single men don't take the women who are so readily available to them very seriously. This could easily stunt their emotional development - for them it's a "narc-creation engine", equivalent to discouraging young XX's from learning to regulate their emotions.
It's not so easy to hold the participants accountable though - they're objectifying
each other. Maybe just take a headcount, assign equal responsibility, and blame the "side" with the most participants /lol.
FWIW I've heard (online) people with the right professional skills and experience say that this is happening, but I haven't seen any data. Definitely plausible though.
If it's just a large pool of narcs enjoying the chaos and uncertainty of each others company, the effect on the new app will be interesting /lol..
