Just spent a few minutes, stumbled across this page too, not sure if this is related to affiliate or not, found via here: http://dannybrown.me/2015/04/01/sorry-affiliate-bloggers-but-your-about-page-disclosure-doesnt-cut-it/
The key part I can see is this
"In addition, it is important for advertisers to draw attention to the disclosure. Consumers may not be looking for — or expecting to find — disclosures. Advertisers are responsible for ensuring that their messages are truthful and not deceptive. Accordingly, disclosures must be communicated effectively so that consumers are likely to notice and understand them in connection with the representations that the disclosures modify. Simply making the disclosure available somewhere in the ad, where some consumers might find it, does not meet the clear and conspicuous standard."
