I can’t remember the News organization that did the reporting, but CSAM content grew a LOT during the pandemic, and learning of this, a news agency wanted to look into it, see how easy it was to find, they tried just doing some basic searches (the search terms for which they didn’t reveal) in major search engines, and turned up a lot of content, specifically in Bing I think off the top of my head. They nearly got in trouble with the FBI because of it. So yeah, if you go looking for it, apparently shockingly easy to come across.
