I think there's also a tendency for the targeting of any given scam/psyop/sales pitch/etc. to make targets look foolish to non-targets. That is, the more narrowly targeted it is to bypass your bullshit filter, the more obvious it seems to someone else. So they walk away from hearing about your situation thinking that they're too smart to be fooled... only to fall for something that was designed to bypass their bullshit filter, possibly without even realizing it.
