They probably got paid a huge amount to promote gambling, but they didn’t think about the consequences. Just imagine losing an account with millions of followers because you promoted an illegal casino. That’s years of hard work gone in an instant, all because of greed.
I want to reiterate this that promoters mostly often do their job because they are being paid for any awareness campaign made for a platform, but as individuals, we are expected to make thorough research about the platform or service we see online being advertised, so that we don't go for the wrong one, making research is very necessary for us to do, because we are going to know why we should go for a platform and the reason why we should avoid such, most times, these platform does not appear the way we see them, except we try them out to know how reliable and reputable.
