You submission has been marked "dead". This means nobody can see it unless they have "showdead" turned on in their profile options. Logged out users cannot see "dead" links. Unless i am recalling incorrectly, you cannot see when your own links have been marked dead.

And why are submissions marked as being dead by default? I find it hard to believe someone is marking it dead - even this question - within less than three seconds.

I'd rather prefer to be banned instead of wasting my time.

It is an anti-spam "feature", basically if a spammer can't tell he is being auto banned he won't try to get around the block. Not sure why you got picked up by the filter.

they are marked dead on a post by post basis, unless (i believe) the account has a history of only posting spam links.

In this case, your link is a duplicate of an earlier/more popular post. So it got auto-deaded

Uh? Is that new? Whenever I posted something already there I got diverted to it. And I believe the older submission got an extra point. That was cool.

Maybe it's different when the older post was marked as being dead? But I hope there isn't such a lack of humour on HN.
