Why might companies face challenges in honoring "do not process" requests?

Companies may face challenges in honoring "do not process" requests primarily due to issues related to legacy systems and regulatory requirements. Legacy systems often consist of outdated technology and processes that are not designed to accommodate modern privacy laws or consumer preferences. These systems might not easily allow for modifications to data handling practices, making it difficult for companies to implement or track such requests effectively.

Additionally, regulatory requirements can complicate matters further. Different jurisdictions might have varying laws about data processing, requiring companies to navigate a complex landscape to ensure compliance. This may involve updating their systems or practices, which can be resource-intensive and challenging, particularly for organizations that have not prioritized data privacy in their infrastructure. These factors collectively create a substantial barrier to fulfilling "do not process" requests effectively and efficiently.
