One of the ways scams and woo spread is by linking a famous person to it, never mind that famous person actually said the EXACT OPPOSITE.
Recently, there was a Twitter debate when someone rehashed the myth that "cancer cannot survive in an alkaline environment", and cited Dr. Otto Warburg, 1931 Nobel Laureate, and even claimed that's what he got the Nobel prize for. But it wasn't.
This alkaline nonsense was thoroughly busted by Snopes back in 2016, as well as by practically every major medical news website and several hospitals and medical schools. To make a long story short, it's circular reasoning. Dr. Warburg actually discovered that cancer cells produce MORE lactic acid by using a different metabolism method than healthy cells. While a cancerous body is slightly acidic than normal, this is the effect of cancer, NOT THE CAUSE. And you can't force a body or blood to be acidic through diet (that means your kidneys have FAILED!). It's clear that whoever listened to this nonsense doesn't understand cause and effect. They think cancer -> acid, then anti-acid = anti-cancer. It doesn't work like that. A caused B. B does not cause A.
But the way they try to validate their nonsense by citing Dr. Warburg via the false citing was the reason for this post. Falsely citing a celebrity is a common scam tactic, usually ignored by the company as that would imply they willingly violated state or Federal laws on False Endorsement and Right of Publicity Claims. In fact, some companies are known to have set up fake news pages claiming links between their products and actors and celebrities such as actor Will Farrell and celebrity chef Paula Dean.
Back in 2004 Actor Ray Liotta sued Nerium after some Nerium reps falsely claimed via Facebook posts that Mr. Liotta's facial complexion improved due to the use of their products. The case was later settled out of court. But this hardly stopped other overeager reps from claiming things that have no basis in science or fact.
One of the more recent victims of false endorsement was Malaysia sprinter Watson Myambek. In November 2018, someone was spreading claims on Facebook that Nyambek is a Bitcoin millionaire to promote some sort of crypto-scam. He categorically denied such allegations and said he will file a report with police and want the lying culprit found.
The point is unless you can trust the source, like a reputable newspaper article, you should NOT believe anything you read on Facebook and similar social media platforms.
