Substantive critique of Facebook is fine on HN. To illustrate the point, I used a moderation mechanism to rescue the OP from being penalized, which is why you see it on the front page now.

That said, you can't do this with an account named "markyuckerberg". We want thoughtful conversation, not cheap shots or personal attacks. Perhaps Zuckerberg needs no protecting when it comes to these things, but HN certainly does, so I've banned this account. If you want to comment on HN, a good place to start would be with a username that doesn't violate the spirit of the site, re which please see https://news.ycombinator.com/newsguidelines.html and https://news.ycombinator.com/newswelcome.html.

Btw, special-purpose accounts aren't allowed here either. We're hoping for good conversation, not pre-existing agendas.

Thanks, Dan! But regardless of one's feelings toward Facebook, I think Mark Zuckerberg should be treated with respect here just like anyone else. Not only is it good for the overall tone of the site, but there are enough "public figures" in tech that use this site that a flat "no personal attacks" (without exceptions for fame) seems like the best policy.

I agree completely. But even for people who don't feel that way, there are good reasons for HN to have this rule. Breaking it degrades the community and oneself.
