As JLT said, the whole "Know Nothing" bit was more about opsec than proud ignorance. Not that I consider them to be a model to emulate, but there were some... issues at my job a few years ago, and someone organized an online group with the name: "XXX Company Employees Against Issue YYYY." Of course there was an infiltrator, and of course they screenshotted everything, but the group name made plausible deniability pretty implausible. Kinda why Ike didn't call it Operation Invade Normandy on the Morning of June 5th (unless the weather is bad, in which case we'll go on the 6th) (p.s. the whole thing about Calais is a decoy) and went with "Overlord" instead. Plus it saved ink and typewriter ribbon.
