Ask HN: Why don't you ban the dead link forever?

Hey,

I notice that dead links can be submitted over and over again!

For example, someone out there keeps sending the Google mozzila homepage. Like here: http://news.ycombinator.com/item?id=505915

If an entry is submitted as dead, do you block the link forever, or you just allow it to be submitted over and over again, and abuse us?

Thanks!

EDIT: If someone submits a link, and you mark it as dead because it's spam, then why don't you make a technique that in case another user submits the same link again, the entry becomes dead automatically?

Also why don't you monitor a "high risk users" with many spam entries? Such users are more likely to be posting spam, so monitoring them - maybe automatically - you will reduce the spam flow here.

Also consider users with no history record as a potential spammers.

Thanks.
