From what you mentioned, I also see that the player is at fault because he did not verify the company he signed with, which led his followers to fall victim to fraud due to his promotion of this fraudulent company. If he cared about his followers, he would not have neglected to check such low-level companies that managed to achieve their goals through him. Likewise, those followers should not have been an easy target for these scammers and should have verified the company, its goals, and its team before investing their money in it.
There are a bunch of e-commerce websites available in my country. Some of them are legit, while others are taking orders, taking the advance, and disappearing after some time by scamming their customers. Also, these e-commerce website later turn their website into an MLM Ponzi scheme. RingID was one of them. They collaborated with international celebrities, and that was a social media platform. Later, they scammed all their users with some kind of investment plans. Even if the celebrities check those website carefully at first, the website later change their business model and scam peoples.
