It occurs to me that if one is concerned about remaining anonymous on Wikipedia, the best way to encourage that is, if someone thinks they've identified you but is in fact wrong, to protest that identification very strongly, to appear to be really concerned about it and try to get it suppressed. That way, everyone will follow the red herring and not look any further.
(not saying this is necessarily true, but noting that effort to suppress does not mean the allegation is true).
Just don't invent PhD's in the process...
