In Street Legends Supplemental, he writes up a profile of Slamm-O! Basically intended it as a slam piece, but he revealed that somehow he had gotten close enough to get pictures of the kid, and the rest was basically a complaint that "he doesn't do it like I do". Slamm-O! didn't fall for the trap, and actually thanked Clockwork for writing the piece. Clockwork, taking that as condescension, threatened the kid, to which Netcat and Fastjack both directly said "Touch the kid and you're dead".
The two things Clockwork has done that has put him in disfavor with a good portion of the network is that he sold Netcat out to the corps, and he threatened Netcat's kid. Most of the time, he's treated as you normally would an internet troll who sometimes has interesting things to say. But those two acts, not the fact that he is racist, are what has made Clockwork a pariah. Those were betrayals of the network itself, while everything else was simply annoying, like dealing with a racist uncle you only see at family gatherings.
