I’m influenced by my favorite celebrities to a point. For example, I’m a big fan of Shaquille O’Neal so when I saw him launch an NFT charity project, I wanted to buy in to support him. I didn’t care about the performance of the NFT or if I made money, but you could say I was influenced to buy it because of his celebrity status. Does this mean I would invest in ShaqCoin or use a gambling platform just because Shaq promoted it? Probably not, but it would likely get me to check it out.
In short, we all could be influenced by our favorite celebrities in whatever they endorsed, advertised, or what they even do on a daily basis. However, it will be our own decision and critical thinking if we will do, copy or even buy what they are promoting. Just as you've said, If Shaq has made his own token such as "shaqcoin" or is gambling on a certain gambling platform, then it will be our own decision if we will be investing or gambling on the same platform, but we have already been influenced by them to check those out.
