I looked through a lot of the comics, there were a few names early on, mainly first names though unfortunately. What I did find later were a user id called CRIME1985 who may know the culprits (he has a youtube n other various accounts online, and hes from canada), the other was a full name Shelley Biermanski, most of comics were pure horseshit though. There were one or two in spanish which started me thinking about a request a while back from a spanish teacher for blank comics, but Im not sure if thats related. Other than that I did the same searches Hatrix did and came up with the same info, sadly no real info on the whois record, though the web host would have full info, and would probably listen to any copyright infringement complaint, though it all depends if Brad wants to go Medieval on his fellow countrymen, because from the looks of it, its probably just some teenage script kiddie showing off for his mates.
Personally though I reckon we should have a good ol' fashioned pitch fork and flaming torch lynching, I haven't had one of those since Thatcher was in charge. Ahh those were the days!
