Personally, for my own value system, I consider the gambling ads to be as bad as scam ads. I think we'll soon come to see the social harm of gambling ads to be as bad as tobacco ads. We should strive for a culture where people see an ad for addictive services or substances and feel an instinctive, pre-conscious disgust. They are the dirty, disgusting, bloodsucking bedbugs of society.
I agree and feel it is a reflection on social decline. While I don’t think prohibition it the way forward it is unsettling that we tolerate this as a society. Would we tolerate youtube advertising for heroin or even recreational marijuana? We certainly don’t for tobacco and we probably shouldn’t for alcohol.
I work in mental health and I am seeing more people who spend a substantial amount on “parlays”. Many examples downplay or hide the behavior from their social network and the extreme examples spend a significant amount. The advertising is obviously predatory and goes against what we know about control dynamics in addict behavior but we tend to view that as a personal moral failing rather than exploiting basic biology and as a result allow the dealer to ruin countless lives before any action is taken (see Purdue and Teva lawsuits)
