Indeed, stats do not convey everything. If it was that easy, then we would simply compare statblocks, declare a winner, and move on.
Of course, you'll notice that, out of all the people profiled in 10 Jackpointers, Street Legends, and Street Legends Supplemental, only a few are actual hackers. Of those, Slamm-O!'s piece was done as a slam by Clockwork, Orbital DK was done by a megacorp, Smiling Bandit was done as an homage by Clockwork, Puck was an homage by Icarus that had very little info that hadn't already been shared in Emergence and Unwired, Rigger X was a slam piece by someone who was pissed at him, Bull did his own, Hannibelle's was fearmongering on Tamanous grounds, and Cerberus made sure his own profile was published. Fastjack isn't about to post his own bio, and even if someone's pissed enough to try and slam him, it isn't going to end up on Jackpoint. And he burned Horizon's info, literally. No, if a bio on Fastjack comes up, it will be done by Bull, Perri, or Captain Chaos's e-ghost.
