Are 'MLM parties' a has-been old-hat tradition that should be put into the dumpster?

Think 'parties' to sell (and sign people up to become sellers/distributors of) Tupperware, sex toys, make-up, women's underwear/lingerie/swimwear, sham health/wellness products, Amway, etc.

I guess people still buy into MLM's just like spam/phishing emails trick people into handing over their private information so until the brakes get applied to the FOMO culture
