Porn, piracy and other questionable sites have always had a lot of fun when it comes to finding advertisers, but it does seem like it's gotten worse over time, encompassing many more sites. It also seems like whether an advertiser is concerned about where exactly their algorithmic ads appear is pretty inconsistent, too.

What I think is interesting is that it seems like Japan is less affected by this. I know I've seen major Japanese companies advertising on sites like Pixiv and Misskey, which have both had some trouble with American payment processors. Heck, I'm pretty sure I've seen Ubiquiti ads when browsing Misskey.

I guess the anglosphere Internet is somewhat impacted by the presence of more "puritan" influence than some other global packets of the Internet. Not 100% sure what to make of that.
