:Sorry for the delay getting back to you. Sure, lets get another opinion. Do you want someone to look a the technical merit of the contributions or just another look at teh conflict of interest issue? I don't know anything about the subject so I'm not qualified to determine if his input is actually valid. I'm just basing my objections on the conflict of interest and the use of multiple IPs.  
 :It's even worse than I thought. 108.67.225.46,207.229.130.243 and 147.126.46.145 are definitely socks of Cdg1072. 108. responded on 4 April to my "Probable socks" post on Cdg's Talk page and wrote in the first person to accuse me of defaming him. Similarly, on 31 March Cdg responded to two unconstructive edit warnings re. Theories of humor on 207.'s Talk page. He says that he proposed the deletions on the article talk page, but that entry was made by 147.126.46.145 on 29 March. It was then rewritten by Cdg on 31 March, AFTER he commented on 207.'s Talk page. 
 :147.126.46.147 is almost certainly another sock. I suspect 64.134.166.22 is also him based on the edits. That IP (from Texas, not Chicago) edited the humor article for about two hours on  25 March (no other history and no overlap with the other accounts' edit times). Cdg and those 5 IPs account for almost all of the edits to this article in the last moonth.  
 :I don't have enough experience to know what to do in a case like this, but this appears to be more than just a case of an editor using his own document as a source. 
 :If we want a technical review of the material perhaps {{:Acadēmica Orientālis]]? He's had some recent input on this topic.
