@corlin It reminds me of a piece I read years ago offering a psychologist's perspective on why obvious scams are still effective.
They are intended to be extreme to get the reasonably sceptical people out of the way early.
When this strategy hits a certain level of public momentum, the grift takes on a life of its own.
It is considered shameful to fall for a scam, so instead people lean into it, and perpetuate the scam on others to justify their own co-opted beliefs and values.
