affliate programs not just casino's are already popular along time ago . why dont you try it now and see if you can earn a profit with them but keep in mind that affliate programs are not easy . you cant just create your own dummy accounts and sign up on your own links because that wont work even if you use some kind of ip changers and vpn . you will only risking your account that can lead to banning .
posting it on popular social media sites like facebook are not also allowed but some unpopular sites and forums do allow them .
