"presenting signs"...there is no way for DK to tell that someone is addicted, which is the same error of logic in the original article.

There are multiple companies that will take your money and data and say they have found a way of identifying gamblers, afaik none of these products actually or can work.

What that article showed is: someone uses a product, they do not activate any features to use the product safely, and then they it is unsafe. DK have safety features integrated with governments already in the product.
