:Just to play devil's advocate a bit.  A different way to treat the material would be to remove it to the Talk page, and have a discussion about it.  Offhand, it seems to me the material is relevant and interesting, and the editor has found a good source to be used in developing this wikipedia article.  Because the editor made a typo is not a reason to be triumphant about banning the person.  About the adequacy of the sourcing, I agree that the material should have been sourced properly:  a complete reference footnote should have been included, and there are better and worse ways to quote/paraphrase/otherwise implement use of the material.  Also, it is somewhat discourteous to fellow editors to put in material and leave it to the others to fix it up (sourcing-wise).  I personally am very disheartened to see pasted in material that is not properly sourced in articles that I work on, and I have personally been involved in very long discussions about the general problem (discussions linked from Talk or Talk archives of wp:plagiarism).  On the other hand, i wonder why the editor should bother to do the hard work of sourcing, if it is likely that enforcer types will strip it all out, anyhow, once they make a judgment that the person is Jvolkblum.  By the way, and as I have stated elsewhere, I don't necessarily agree that this person is the original Jvolkblum.  It could be that this editor has some overlapping interests (and/or may be from the same geo area) and was swept up unfairly in the accusations about Jvolkblum socks.  Then, once labelled a sock and treated badly, I don't know what good alternative there would be for a would-be editor, besides going ahead and creating new accounts as needed to continue editing.  It seems that Wknight94 and others have engaged in a big game with the user(s).  I guess I would suggest trying to make a truce and stop the big game.  Instead, I imagine it would be a lot better for this Suburb article for there to be intelligent discussion on the Talk page about the material, how best to use it, how best to quote / paraphrase / restate it, etc.
