Probably just cause the scam lists don't have you under gambling? Scammers kind of have a dump list of info afaik about the people they send stuff like this, and most of the time it's related to whatever activity they were doing recently, maybe up to the past 1 year at least?  Never had this thing though probably cause I use a dump email for my casino accounts, my main account usually just receive spam emails and promotions from frigging news sites and whatnot lol.

Also, phishing scams still happen yes but most of the time they're done live no? Like as a customer support call or something.
