I don't really get the problem with doing a paid promotion for a stock. If Alex did receive payment the first time and didn't disclose then I would agree that is wrong (and sounds like illegal). This latest video isn't a massive scam. He was abundantly clear that he is being paid. Alex was also clear that POET is pre-revenue.
It is pretty impressive/slightly odd that Chris had a whole video recorded and published within 24 hours of Alex posting his.
It would be really funny/very good for my account if POET announced Celestial AI orders this week.
