SCENARIO
Please use the following to answer the next question:
Brady is a computer programmer based in New Zealand who has been running his own business for two years. Brady's business provides a low-cost suite of services to customers throughout the European Economic Area (EEA). The services are targeted towards new and aspiring small business owners. Brady's company, called Brady Box, provides web page design services, a Social Networking Service (SNS) and consulting services that help people manage their own online stores.
Unfortunately, Brady has been receiving some complaints. A customer named Anna recently uploaded her plans for a new product onto Brady Box's chat area, which is open to public viewing. Although she realized her mistake two weeks later and removed the document, Anna is holding Brady Box responsible for not noticing the error through regular monitoring of the website. Brady believes he should not be held liable.
Another customer, Felipe, was alarmed to discover that his personal information was transferred to a third- party contractor called Hermes Designs and worries that sensitive information regarding his business plans may be misused. Brady does not believe he violated European privacy rules. He provides a privacy notice to all of his customers explicitly stating that personal data may be transferred to specific third parties in fulfillment of a requested service. Felipe says he read the privacy notice but that it was long and complicated Brady continues to insist that Felipe has no need to be concerned, as he can personally vouch for the integrity of Hermes Designs. In fact, Hermes Designs has taken the initiative to create sample customized banner advertisements for customers like Felipe. Brady is happy to provide a link to the example banner ads, now posted on the Hermes Designs webpage. Hermes Designs plans on following up with direct marketing to these customers.
Brady was surprised when another customer, Serge, expressed his dismay that a quotation by him is being used within a graphic collage on Brady Box's home webpage. The quotation is attributed to Serge by first and last name. Brady, however, was not worried about any sort of litigation. He wrote back to Serge to let him know that he found the quotation within Brady Box's Social Networking Service (SNS), as Serge himself had posted the quotation. In his response, Brady did offer to remove the quotation as a courtesy.
Despite some customer complaints, Brady's business is flourishing. He even supplements his income through online behavioral advertising (OBA) via a third-party ad network with whom he has set clearly defined roles. Brady is pleased that, although some customers are not explicitly aware of the OBA, the advertisements contain useful products and services.
Based on current trends in European privacy practices, which aspect of Brady Box' Online Behavioral Advertising (OBA) is most likely to be insufficient if the company becomes established in Europe?

SCENARIO
Please use the following to answer the next question:
Ben is a member of the fitness club STAYFIT. This company has branches in many EU member states, but for the purposes of the GDPR maintains its primary establishment in France. Ben lives in Newry, Northern Ireland (part of the U.K.), and commutes across the border to work in Dundalk, Ireland. Two years ago while on a business trip, Ben was photographed while working out at a branch of STAYFIT in Frankfurt, Germany. At the time, Ben gave his consent to being included in the photograph, since he was told that it would be used for promotional purposes only. Since then, the photograph has been used in the club's U.K. brochures, and it features in the landing page of its U.K. website. However, the fitness club has recently fallen into disrepute due to widespread mistreatment of members at various branches of the club in several EU member states. As a result, Ben no longer feels comfortable with his photograph being publicly associated with the fitness club.
After numerous failed attempts to book an appointment with the manager of the local branch to discuss this matter, Ben sends a letter to STAYFIT requesting that his image be removed from the website and all promotional materials. Months pass and Ben, having received no acknowledgment of his request, becomes very anxious about this matter. After repeatedly failing to contact STAYFIT through alternate channels, he decides to take action against the company.
Ben contacts the U.K. Information Commissioner's Office ('ICO' - the U.K.'s supervisory authority) to lodge a complaint about this matter.
Assuming that multiple STAYFIT branches across several EU countries are acting as separate data controllers, and that each of those branches were responsible for mishandling Ben's request, how may Ben proceed in order to seek compensation?
