>>In fact someone who wanted Kevin to be taken as the perpetrator might well have chosen it on purpose.
In which case the subterferge did indeed span months.
My advice would be to review M's initial posts again, dissecting every point he made and considering what he's telling the culprit and why, if not to incentivize them to come clean. E.g. he makes quite a point about initial valid registration details: why is that important?
"... 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
