I don't let celebrities manipulate my trades anyway. It is just like those who endorse products in commercials, and it doesn't make any product even more better to its quality just because someone promoted it in TV.
I do not know who those people are, but I would advise people to stay away in these popular platforms when looking for crypto news or any inspiration to those who succeed. Not even a Report button would help purge those who spread fake contents anyway. Many people post random referrals out there and it isn't that regulated immediately especially in Facebook wherein I receive random giveaway links but turned out to be terminated by the Support Team 2 days later.
