It made headlines not long ago when Just-Eat I believe was advertising on porn sites, so it's not an impossible ask... but marketers will want to play those campaigns very carefully. It wouldn't take much to accidentally end up next to revenge porn that makes the news or something.

Can you elaborate further? why is this the marketer's problem?

why isn't the ad campaigner completely agnostic on where the ad network sends it?

to me, it seems like widespread conjecture. out of the things I've seen people talk about boycotting a brand for, showing up in a banner on a porn site hasn't been one of them. People know how targeting works, their session and the ad networks.

is there a case study supporting marketer's skittishness?

Not the original commenter but it's because the marketer doesn't want to be associated with the content. It may devalue the product, be the wrong target audience, cause some social media backlash, etc. (e.g. Disney wouldn't want to advertise Disney+ on a revenge porn page since it would ruin their family-friendly image).

People in your network maybe. If that were widely true you wouldn't see people swearing that FB is listening to you for showing a mattress ad after you spent an hour searching for it on your computer. The average American has no idea what the hell is going on.

The only situations I'm aware of of general brand contamination are the @stopfundinghate ones, and that's very different - pointing out to brands when their stuff is appearing next to far right content.
