These tools are often hobby projects. The original developer may lose interest, lack time to fix a major API change, or simply fail to renew the domain name. Domain expiration—where fbdown.net becomes a parked landing page—is a frequent final state.

Meta explicitly prohibits automated scraping and downloading of content without authorization. The company maintains a legal team that sends cease-and-desist letters to operators of such services. In many documented cases, site operators voluntarily shut down rather than face litigation, leading to permanent downtime.

The primary existential threat to FBDown.net is copyright law. Although downloading personal content may be permissible, the service is widely used to repost copyrighted videos (e.g., music clips, TV shows). Rights holders issue Digital Millennium Copyright Act (DMCA) subpoenas to domain registrars and hosting providers. Once a host receives a complaint, they often suspend the entire server, causing "down" status for all users.
