99% of complaints come from dating app addicted people, you spotted that right, congrats. Its a good observation.
These systems were investigated in detail 15 years ago, and all data produced about plentyoffish is perfectly adaptable to the reality we live now, because the bulk of the knowledge was built decades ago.
Basically the core of the info was established during the 2000s when there was badoo and matchgroup and when fecesbook came out there were agencies that followed american pie theory to the letter.
It was also analyzed to death by the first incels, the most famous one is paragon, read his blog here:

His blogposts didnt update simply because the knowledge does not needs update. The info can be found also elsewhere, in comment sections of older blogs and forums from 15 years ago.
There are problems based on incentives and low value users, and the impossibility to match low value users. The people involved in this stuff have access to a base of info that is quite established. Andrew tate didnt do anything fancy, he simply learned the info and he repackages it for the low attention span normies who dont bother to do a research.
But anyway, yes is true, the majority of people who complain about dating apps are those who cannot read, those who cannot learn from history and cannot and will not change their behavior even when presented with evidence and true info.
Since normies exist, since they are a part of our reality, then scam, fraud and theft will also always exist.
