I agree, a lot of these so-called influencers do this kind of fake marketing and it should be punished by law, in my opinion. It would seem to me that these kind of people have learned a trick or two from the "day-trading" influencers who "teach" people how to do technical analysis and how to make daily profits by selling them a course they have to pay a fee for.
We really need laws so people won't do this crap.
