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.
