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

Understandable, but I think there should be some discriminating system for another class of sites, the "you can submit but not discuss" ones.

For example, a recent submission (of mine):

"Luis Buñuel: The Master of Film Surrealism"

it had no discussion space because (I guess) it comes from fairobserver.com . Now, I understand that fairobserver.com may had been an hive of dubious publishing historically, but it makes little sense we cannot discuss Buñuel...

Maybe a rough discriminator (function approximator, Bayesian etc.) could try and decide (based at least on the title) whether a submission from "weak editorial board" sites seems to be material to allow posts or not.

Oh I agree - >>36924205 was a fine submission. Can you please email hn@ycombinator.com so I can send you a repost invite for it?

That domain is a borderline case. Sometimes the leopard really changes its spots, i.e. a site goes from offtopic or spam to one that at least occasionally produces good-for-HN articles. In such cases we simply unban it. Other times, the general content is still so bad for HN that we have to rely on users to vouch for the occasional good submission, or to email us and get us to restore it. I can't quite tell where fairobserver.com is on this spectrum because the most recent submission (yours) is good, the previous one (from 7 months ago) is borderline, and before that it was definitely not good. But I've unbanned it now and moved it into the downweighted category, i.e. one notch less penalized.
