At our monastery, Anonymous Monk is everybody who doesn't wear robes.

The anonymous posters are all naked? That doesn't sound like the behavior of somebody with above-average privacy concerns. Though we do occasionally get anonymous visitors who behave a bit like streakers. But they are a distinct minority, IMHO.

Robes that convey identity rather than conceal it? Perhaps monogrammed robes? This place never struck me as a spa or over-the-top hotel.

A bunch of faceless volunteers dressed in identical robes calling each other by the same generic name ("Brother") while transcribing wisdom without signing their names. I just don't see how anonymity is antithetical to monkly attire. Nor to monkly ethos (to touch on a previous subject).

The root of this thread said "past abuses of the Anonymous Monk robe". So I'm not the only one who finds your use of "robes" reversed.

But the whole Monasterial theme is just for amusement. The analogy falls over quickly.

Whether anonymity matches monkly ethos seems completely irrelevant to me. My concerns tend to be more on the practical side. I think they mostly boil down to encouraging constructive contribution and discouraging disruptive contribution.
