I know there is usually a “target demographic” that is profiled for what kind of products that they may buy. I was listening to an electro swing mix online and I kept hearing ads for different kinds of soaps, and all I could think of is “damn, a lot of people must clean while listening to this.
If it’s anti-LGBT stuff, that may be because major ad systems e.g. Google/YouTube don’t treat LGBT as a demographic but rather a topic of interest … and the far right are interested.
