Yeah, he's explained that he's involved with the story, which would mean that he has first-hand information. Not that you'd want that. People with first-hand information and who claim to be involved with a story should identify themselves else why should we believe their first-hand accounts.
Especially when they claim to be a named source in the WP.
Do I have to point out to you the obvious fact that somebody who identifies himself exposes himself to retaliation?
