>>His belief, and mine as well, is that "Grover" 1) acted for unknown reasons; and 2) faked Michel out completely. For sure we don't know how or why it was done. There are any number of possible scenarios besides the one you describe. Kevin could have been chosen semi-randomly as a high profile forum member.
Do you have examples of this ever happening before in real life? I know there are plenty of thrillers where false trails are laid to implicate the butler or for revenge by a jilted lover, but we're talking about a tricky online subterfuge lasting months and requiring a monumental investment of effort for such a petty result.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
