It sounds like his platform is perhaps a private enterprise platform? In other words, it doesn't sound like Facebook or Youtube where information can easily spread, which is probably a prerequisite for having control over your data. The company I work for deals with background checks and screening information on behalf of our clients' clients. I could definitely see us safely removing all of that personal information from our system and not being able to recover it. But at the same time, we're a much much much smaller organization compared to Facebook.
