Seriously? No. I may dislike what LulzSec is doing to portions of the Internet, but you can't just lump "trolling" with something as serious as antisocial personality disorder or conduct disorder.
Plus, a large majority of people suffering from ASPD are already in jail for one reason or another - violent crimes, typically. LulzSec probably consists of a wider range of individuals than we imagine.
Okay, maybe my statement was a little hyperbolic, but forgive my ignorance (iirc, psychology is your forte? Unless I'm mistaken). "Trolling" in maybe the full definition may not be so sinister, but there are some people that get kicks from doing or saying incendiary things just to get people all wound up and can lead to things like cyberbullying in some cases. Add on top of this the tendency for some internet goers to trick people into seeing explicit imagery (the "raid" on youtube where tons of porm was uploaded in a misleading fashion. Disguised as pop culture videos.) that could be considered public indecency, exposure to minors, or some internet equivalent. And then there's this, a bunch of script kiddies going around causing problems out of some sick sense of enjoyment. Any of these could be considered illegal. While this disregards the real life portion of their existence, I highly doubt they are much more mature in any face to face situation.
So maybe most wouldn't meet the full definition of either of those disorders, but I think there is most definitely something wrong with them on an individual basis. Either way, you cannot deny these individuals are acting solely in an anti-social manner.
