Ask HN: LinkedIn Pyramid Scheme?

I am being contacted by a lot of random people on LinkedIn who claim they want to help me build assets so that I don't have to depend on my paycheque. All of them want to set up a zoom call to develop "trust and transaparency". All of them will also vehemently deny writing their proposal to build assets on LinkedIn. My spidy sense tells me this is some kind of a pyramid scheme. Does anyone happen to know what this is about? I am genuinely curious as to what this is!
