Searching for "the black team ibm -mustaches -infamous" on google returns (nearly) nothing. I find it astonishing that there is no record of such a team that doesn't mention mustache twirling.

I suspect that some hacker wanted a version of the Black Watch to look up to, so he invented one. I don't object to the invention of legends, but we should include some traditional legend-flagging phrases: "long ago", "never heard from again", &c.
