There are gambling companies who are using all this surveillance ad tech and AI to retarget gambling addicts who are trying to quit. This will also apply to other addictions. So if you are trying to quit drinking, you will still be in the "interested in alcohol" segmentation and will get a lot of ads and coupons for alcohol. Struggling with your weight? If those ad companies are noticing that and they will, you will get ads for sweets and ads shaming you for being fat trying to sell you quack medicine.
