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.
