I mainly try to see if they are just being duped into promoting bullshit or if they know that it's bullshit and still promote it. If they never recant their bullshit claims, or even double down on them. Also if they react with hostility to people questioning them or ignore the questions entirely. And to your point about asking for money, the way social media works right now you can get money for clicks, follows, and views, so that does play into things
