They for sure create targeted advertising towards likely repeat-spend customers. Big box liquor stores I’m sure use algorithms to encourage repeat purchases.

Again - not defending predatory gambling sites at all - just aware that almost every business model is about targeting big spenders and getting them to spend more. Example: micro transactions in gaming.

“Everyone does it” doesn’t make it ok, but if we don’t like that gambling sites care more about profit than the wellbeing of users? Certainly they are not alone in that.
