<messaging> A semi-mythical being that cancels Usenet articles posted by others. (In general, an article can only be cancelled by its original author.)
The Cancelmoose's usual target is spam or extremely excessive cross-posting.
Some believe that the Cancelmoose exists only in the same mythic sense that B1FF, the NSA line eater and Shub Internet exist; others consider Cancelmoose's historicity to be closer to that of Kibo. The latter group assume that the real Cancelmoose is not one person (or moose), but instead is a cabal of NNTP wonks. However, the Cancelmoose is probably real, seeing as how it has its own website.
