 :::::::Well, Rockbaum edited for a grand total of 6 minutes in 2008 and was then indef-blocked without prior warning (or any communication). Making him revert to that account and fill out an unblock request admitting to being immature 5 years ago seems like process for the sake of process, so I think ignoring the technical block evasion and informing him about copyright was the most sensible thing to do. :::::::I'm still puzzling over the second bit. , ,   and a number of others appear to have done a bunch of editing (sometimes collaborative) in user space. From the way some of them started their user pages (short one-sentence factoid about themselves), I suspect they're from a 2011 iteration in this class. I've checked those 4, and none of them have significant 2011 article space contributions or any deleted contributions. In other words, they wrote articles on their user pages but never moved them to article space. They all show up in Google searches, so Ricbaum may have copy-and-pasted from there; it doesn't look like there's been any concerted effort to move the 2011 material into article space.
