Different jurisdictions have taken different approaches to privacy issues with advertising. The United States has specific restrictions on online tracking of children in the Children's Online Privacy Protection Act (COPPA),:16–17 and the FTC has recently expanded its interpretation of COPPA to include requiring ad networks to obtain parental consent before knowingly tracking kids. Otherwise, the U.S. Federal Trade Commission frequently supports industry self-regulation, although increasingly it has been undertaking enforcement actions related to online privacy and security. The FTC has also been pushing for industry consensus about possible Do Not Track legislation.
It is important to note, however, that StudioPress is now a subsidiary of WPEngine which is the company that actually does the web hosting on which StudioPress’s Genesis framework runs. The affiliate program only works with choosing the StudioPress framework and themes, not the actual hosting on WPEngine. WPEngine has a separate affiliate program for its hosting services, which yes, is a bit confusing.
Affiliate marketing overlaps with other Internet marketing methods to some degree, because affiliates often use regular advertising methods. Those methods include organic search engine optimization (SEO), paid search engine marketing (PPC – Pay Per Click), e-mail marketing, content marketing, and (in some sense) display advertising. On the other hand, affiliates sometimes use less orthodox techniques, such as publishing reviews of products or services offered by a partner.
In 2009, Bluehost introduced a new feature called CPU throttling. CPU throttling (at Bluehost and similar hosting services) refers to the process of reducing user's CPU usage in whenever the particular user is pulling "too much" server resources at one time. At that particular time, Bluehost would freeze (or drastically reduce) client sites' CPU usage substantially. This effectively shut down clients' websites hosted on the Bluehost server for several hours throughout the day.
