Lurking doesn't require an account.

I admit, my comment was a little short-sighted in a way. However, I think someone should be an active member of a community like HN in order to make such a judgement (i.e. not appropriate for HN).

Beyond that, the guidlines say not to post such comments and I strongly agree with it. Should've just downmod it in the first place...

How long ago somebody made their account should not be a factor in judging their contribution. Or lack thereof...

Have you read the guidelines for HN yet? http://ycombinator.com/newsguidelines.html
