In a regulatory filing, Facebook said that it anticipates that its ongoing investments in safety, security, and content review will identify additional instances of misuse of user data or other undesirable activity by third parties on its platform. "In addition to our efforts to mitigate cybersecurity risks, we are making significant investments in safety, security, and content review efforts to combat misuse of our services and user data by third parties, including investigations and audits of platform applications that previously accessed information of a large number of users of our services," the company said in the filing. "As a result of these efforts we anticipate that we will discover and announce additional incidents of misuse of user data or other undesirable activity by third parties. We may also be notified of such incidents or activity via the media or other third parties. Such incidents and activities may include the use of user data in a manner inconsistent with our terms or policies, the existence of false or undesirable user accounts, election interference, improper ad purchases, activities that threaten people's safety on- or offline, or instances of spamming, scraping, or spreading misinformation. The discovery of the foregoing may negatively affect user trust and engagement, harm our reputation and brands, and adversely affect our business and financial results. Any such discoveries may also subject us to additional litigation and regulatory inquiries, which could subject us to monetary penalties and damages, divert management's time and attention, and lead to enhanced regulatory oversight."
