I took a look at his edits, and he's been back since the 4th. So far only two of his edits have been about the adult scene: the Jenna Jameson article, and the Joey Yale article. The first you knew about, the second was his classic link removal job and had already been reverted. All his other edits have been to sundry athlete articles, where he seems to be adding details about their high school years which is okay by my book...
