Grift poorly defined? https://www.merriam-webster.com/dictionary/grift

But this guy's talking about drop-shippers, life coaches, cryptocurrency, online "influencing" in general, and other things. Very few of those fit your own definition, as there's nothing illicit involved.

In some cases, e.g. if you compare cryptocurrency to drop-shipping, there's not even much common ground, except "markets things through social media."
