And I added attribution and background info on the talk page,
Talk:Graffiti4Hire (T-H-L-K-D), so that should probably be good enough, since it is a part of that page's history, even if it is the Talk page.
Interesting side-question - whether or not it's "good enough" probably depends on who wrote the original text, and how easily that person takes offense at such things. In any event, it would definitely be better if some helpful admin would add the attribution to the original edit summary anyway, just to cover the bases, so to speak. There are probably at least a dozen admins who would be willing to do it, even if it were known that Mr. Kohs wrote the original article text (which I seriously doubt, in this case - in fact, I'd say the chances of him being the author of this particular article/stub are very close to zero).
