I am hoping that people who gamble can still prevent themselves from being addicted on it, there are still a lot of things that we can do to prevent addiction and those gambling websites or application can also help their customer by doing these things.
1. They can use more secured ways to identify the real identity of their customer, the best thing to do here, aside from valid ID is they should add "take a selfie" on identity process.
2. They can also set a time limit of playing for a player, give notification if this would be their last game anymore for today.
3. Set a notification showing how long they've been playing.
With these kind of features, they might actually help or lessen the addiction of a gambler.
Just think in the practical way, do you think it's an impossible task for someone to pass selfie restriction when they really want to gamble? They can throw a 10 dollar bill to someone and make them to be their pseudo identity. So if we really need to stop them then all time face surveillance can be the realistic choice to prevent the minors from gambling.
Time limit won't be effective because someone can bet a million dollar in single bet and lose all at once so instead of thinking that sites should stop the addiction why the individuals can't stop being ignorant with their actions.
