The current listing at VfD of [[Cayley-Newbirth operation matrix]] has flushed out User:ExplorerCDT, who at the very least knew this was a hoax page, and posted comments at VfD designed to obfuscate and mislead.
User:ExplorerCDT is apparently otherwise in good standing as a Wikipedian. How to proceed in such a case?
Context is that there have been a number of attempts to place hoax pages in mathematics in the English Wikipedia. This example is evidently written with at least a well-informed graduate student knowledge (as with the recent vandalism attack by [[User:Slim Jim]], with plausibe disinformative tweaking). The page was been around for eight months, since it has the look-and-feel of a piece of obscure, dull abstract mathematics quite accurately.
For myself I would like to see User:ExplorerCDT banned, for bad faith editing.
