Yeah, like the other guy said about Firefox android, I normally use Firefox focus and I saw "0 ads". Maybe it'd because of pihole but I suppose focus does a good job by itself.
People need to forget using chrome on android at least
Sometimes these slightly-NSFW ads are what you get when you're heavy on ad blockers and such, because they're buying out the lowest/cheapest ad tiers where there isn't much targeting data available.
I'm definitely heavy on blockers and I didn't see any ad there (and basically anywhere else,) only the article text and pictures. I'm using Firefox and UBlock Origin on Android.
