Hi,
The targeted person's reaction is secondary to him. And the targets are, most likely, chosen at random. He is more stimulated by seeing his work there, in print, than anything else. It's like some persons who write graffiti on a wall; they are less interested in the reactions of those who see it, than in looking up and seeing that their work is there. And only strong outside intervention will even begin to stop him.
What amazes me is that this guy, a 19-year-old, whose identity is known publicly, is willing to risk his future career life by engaging in silly, disruptive, petty vandalism that would be common from a two-year-old.
And what he's doing is illegal, too. He's taking a huge risk.
Why can't some people simply apologise and move on, or at least move on? There are other things that are far more worthy of one's time, Wikipedia-related and not.
