Some people only receives offers to promote for a platform in which they don't care to know how reliable they have been or not, once they have agreed terms and conditions with them to work and get paid, now left for everyone of us to take time in making research on which platform to go for and the ones to avoid before using them.
They'll only shown with how much money they'll get paid for and they wouldn't care whether they're advertising an illegal or legal casino. The only promise they'll get is the promised money to them. After that, it's all by yourselves and it won't matter to them if the casino turns south and bites the dust. While the players that have trusted them might blame them for that, but they'll reason out that they're just paid to promote them and give them reminder to 'gamble responsibly'.
