Absolutely. My uncle got taken by an “investment club” supposedly endorsed by Warren Buffet and run day to day by some real financial person.

All communications were via WhatsApp. They started with real stock tips (which were pretty good actually!) and then did a pump and dump.

I received a similar ad (mine was from the shark tank people), reported it and got a message similar to what you described. They were obviously stealing Mark Cuban’s likeness and peddling an obvious scam.
