The guy is not a hacker, he's doing his job, which is to generate posts with links on high quality sites lik bpl, if possible. He uses software to do that, there's no hacking involved. You can buy it too, it costs about 600 bucks retail. He makes his living doing this, it's his job, just as you make your living doing whatever it is you do to earn a living. He'd use different user names if the forums were moderated better, but since bpl is letting him use the same one, that's even easier for him, he'll post stuff until that user name dies, then generate a new one, takes him no time.
That's a very good tool too by the way, good quality programming, assuming it's the one I think it is.
