I think wikipedia editors should be forced to reveal their identity and picture ( KYC)
As a counter, I knew a rather active en.wikipedia admin[1] who -on joining google+ - had to reveal her real name at the time. Immediately she got doxed and people harassed her boss, her grandparents, and her family. This was somewhat to be expected, because there will always be a contingent of people who are unhappy with authority, especially those who are are subject to it. Would you argue that the harassment allowed her to keep a clear judgement, improved her understanding of policy, or otherwise made her a better admin?
You first.
We can't bring that threat under control while remaining completely ignorant of the people involved.
