Fraudulent Advertising on Facebook
Not to defend Facebook for not doing their due diligence, but this article is really underselling the complexity of the problem. The pseudocode given:<p>if (display_domain == landing_page_domain)
{
 approve_ad = true;
}else{
approve_ad = false;
}<p>is, for one thing, not robust against cloaking (if malicious advertisers see the request coming from a Facebook IP, they might actually redirect to the displayed domain).
