In the past, it was noticed that through bulk SMSes, investors were induced to invest in or purchase the stocks of certain listed companies. Such instructions could actually endanger people — citizens receive air strike warnings via smartphone alerts. This ability to mix the public and the private, as well as the ability to use bots to engage with users has proved to be problematic. In early 2021, a database selling phone numbers pulled from Facebook was selling numbers for $20 per lookup. Similarly, security researchers found a network of deepfake bots on the platform that were generating images of people submitted by users to create non-consensual imagery, some of which involved children. Although some channels have been removed, the curation process is considered opaque and insufficient by analysts. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content.
