Problem: Functionaries get doxxed on and off Wikimedia projects, and receive threats of harm and have had things happen to them in real life. Many countries, including the United States, do not have proper legal protections regarding publication of private information, and county and state records including birth certificate and property deed information wind up on data sharing sites.
Proposed solution: For functionaries, provide an identity protection service like DeleteMe and/or general identity theft protection (plenty of companies do this in the US). Provide equivalent services in other countries. Also write up a guide as to basic identity protection practices (there are plenty out there for high-risk journalists, for example).
Who would benefit: Functionaries, and users served by those functionaries.
More comments: It might be possible to convince companies to provide this service as a gesture of goodwill and charity.
