If I understand correctly, the credibility of advertising is a real issue. That's where I've noted companies like Facebook and Google exiting from certain ad markets or restricting ad options for certain keywords, such as “cryptocurrency” and “opioid addiction treatment centre”.
I think it's very important to recognize that this is a clear limitation when you have some of these algorithmic markets being constituted. It's that they suffer at times from being able to recognize quality or credible information.
I think that is one of the ubiquitous problems that we have. To operate at scale, information triage has kind of taken on a market-like approach. I think that it has often failed in delivering high-quality ads, or at least with opioid addiction treatment centres, ads that aren't from scammers or dubious treatment centres.
I think that's an important finding. It's important to recognize that there are real challenges in how algorithmic recommendation takes place and whether that functions effectively in being able to discern what's good and bad information, to use those terms super-loosely.
