Why not. Do you really think the site improves if every Anonymous Monk post has JimDDDD (with DDDD the node-id) as an author instead?
To me, total anonymity—or, more precisely, shared, ambiguous and amorphous identity—doesn't jibe with the monastic ethos.
Right. It's so much better if everyone on this planet can pick any name they want, as many times as they want. Then we all know instantly who everyone is. "Jim" can only be one person.
The old saying goes "On the Internet, noone knows you are a dog". That doesn't go away if you're forcing dogs to pick nicknames.
What purpose does a sophisticated voting system
Sophisticated voting system? Where? There's a voting system here, but I wouldn't call that sophisticated. And isn't the official standpoint that XP is a game?
Besides, Anonymous Monks don't get to vote. If you're forcing people to use throw away accounts, they'll get votes. So they can vote on posts make with their previous throw away account. Really think that's a good idea?
I've no problem with anonymous monks. But you're free to not read their posts (and specially, to not answer them). If this were usenet, your reader could automatically filter out posts made by people you don't want to read (except that usenet doesn't have a marked anonymous user).
