Does affiliate program refers to someone endorsing the casino?
Sincerely speaking I have seen lots of these social media influencers doing affiliate marketing whereby they post their ref code or link together in their post, this doesn't mean that they are solely reliable for those who are signing up for the website. There is different between a representative and affiliate marketer, this person gets his code or link share but due to how they are influencial people would go signed up and start making use of the website this doesn't mean that if anyone Lose their money the influencer will be hold responsible.
I can also reference other case that relates with Elon musk tweeting about some memecoin, he doesn't directly asked you to go put your live saving in those projects, hence if the coin dump you won't hold him responsible for the lost but he tweeted about the coin that's was why many people who bought dogecoin when tweeted lose lot of money with the mindset that the coin would eventually gets to 1$ but it fails and lot of people lost money.
Elon Musk tweeting about doge coin cannot be used as a reference here. He has no legal bindings with the project. We all know why he was doing that, it seemed he had a huge amount of doge and wanted to cause FUD that will increase the price so he can sell.
An example which is relatable is this; You wear a signature for a casino, you promote their services and new users get to know about the platform through your advertisements. Don’t you think you have a moral obligation to use your signature space wisely and promote projects which you believe are legitimate and align with your values?
Well there is nothing much to extend this discussion more longer to me, because if you promotes a project as you may have said it, you believed in that project and it happens that you are using their services without any issues or problems and someone else signup and started using that same casino through you, what if that person violate their terms and conditions where that person account is disable or frozen would you still be responsible for their mistakes or errors?
No! you aren't in any way to be held responsible for not follow the rules and regulation of the casino, hence if additional verification is needed is not you that is going to provides those details rather than the user who signed up through your affiliate links. What are my trying to say here?
As a marketer and people has followed your affiliate link to signup, the next is for them to adhere strictly on the casino rules and regulations not relying on you who ref them to signup on the casino, therefore they should do whatever findings for themselves and also calm down to read whatever thing that is needed to make their account secured and passed all necessary kyc's required if applicable. That is all!
