Have you tried doing this using a couple of websites [that you own]?
Already did, but as for my own experience people just ignore my links
Only my friends are trying to use the links that I gave and been providing whenever I do this things on the past. This affiliate thing is also like here, reputation is a must, if you're just an ordinary individual without any colleagues affiliates won't work at your cause.Without having a huge visitor, we are hard to gain a referral from the affiliate links, but it's not impossible. Once I tried to spread about a product using my affiliate links, and I only got a few referrals that join under me.
And if we want to spread affiliate for the casino, then I think we need to work hard and spread in many places including in the gambling website or gambling forum so we can get a chance to get a referral.
Perhaps, making a video about we played a game could be a good idea to try but we need to have a big follower so they can watch the video, they are seeking to join in the gambling site, they deposit coins or money so we can get the bonus affiliate. But we need and must to remember them that gambling can cause addiction, play with responsibilities.
