This has raised larger questions in my mind . As a software engineer I ' ve developed very sensitive systems that track changes to key information to provide an audit history . There is separation of authority between developers and database administrators . None of the developers even have access to production data we stub data for them . This and more is all standard stuff when dealing with PII and conforming to HIPPA , but what about social media ? Does Facebook gag , for example , take these steps to prevent falsifying user content ? Twitter ? Because people have been arrested and convicted of crimes related to the content they ' ve published on these platforms . I think it ' s time for decentralized hashing or something similar , and I think the entire industry should lobby for and adopt an open solution to the problem .
