Tell HN: t.co is adding a five-second delay to some domains

>>xslowz+(OP)
I think that HN itself also shadow flags submissions from a list of domains it doesn't like.

Try submitting a URL from the following domains, and it will be automatically flagged (but you can't see it's flagged unless you log out):

  - archive.is
  - watcher.guru
  - stacker.news
  - zerohedge.com
  - freebeacon.com
  - thefederalist.com
  - breitbart.com

Well, yes, many sites are banned on HN. Others are penalized (see e.g. https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...). None of this is secret, though we don't publish the lists themselves.

Edit: about 67k sites are banned on HN. Here's a random selection of 10 of them:

  vodlockertv.com
  biggboss.org
  infoocode.com
  newyorkpersonalinjuryattorneyblog.com
  moringajuice.wordpress.com
  surrogacymumbai.com
  maximizedlivingdrlabrecque.com
  radio.com
  gossipcare.com
  tecteem.com

Do you have get-out-of-jail or N-strikes-and-you're-out policies? What if someone's legitimate website gets caught in this? I've also long wondered about user specific shadow bans. Can you please shed light on this?

There's no automatic unban. That would require writing code that knows how to tell a good (for HN) site apart from a bad one, and if we could write such code, we wouldn't need to keep a list of banned sites in the first place. However, we're always happy to unban a site when we notice that it's actually fine for HN, or when someone points this out to us.

Re shadowbanning (i.e. banning a user without telling them), see the past explanations at https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que... and let me know if you still have questions. The short version is that when an account has an established history, we tell them we're banning them and why. We only shadowban when it's a spammer or a new account that we have reason to guess is a serial abuser.

Thanks for the thoughtful reply. Is it also true that users with certain karma count or special permissions have more significant - and potentially lasting - downvoting weight that impacts to the downvoted party's long term reputation?

I'm afraid I don't understand your question but here are the basics: HN has downvotes (on comments, not submissions). The ability to downvote requires > 500 karma. When a comment gets downvoted, both its point score and the commenter's karma go down (in most cases - it's more complicated than that but this is the principle). Does that help?
