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.
It's called market and I don't think the law has anything to do with it unless if it's done against the law. Moreover nobody is force to click or follow what these influencers are doing and most time you are being warned to take your own decision when it's comes to these kind of marketing.
You will see a lots of them on youtube with different tricks of attracting people to click and join what they are influencing.
