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

Would be nice if the lists were published though with a link to the list from the submission form.

The problem is that if you publish the lists it leads to more abuses. For example if spammers find out which sites are banned then they just post other ones.

I think there are two different types of sites you are blocking: (1) those which are just pure spam; (2) news/opinion/etc websites that you’ve decided are not suitable for HN for various reasons (such as being low quality and tending to produce more ideological flame-wars than curiosity), for example Breitbart

I agree that publishing case (1) causes harm (spammers will just use a different domain if they know you’ve blocked theirs.) But case (2) is rather different. I don’t think the same justification for lack of transparency exists in this case. And I think shadow-banning the submission in case (2) is not very user-friendly. It would be better to just display an error, e.g. “submissions from this site are blocked because we do not believe it is suitable for HN” (or whatever). A new user might post stuff like (2) out of misunderstanding what the site is about rather than malevolence, so better to directly educate them than potentially leave them ignorant. Also, while Breitbart is rather obviously garbage, since we don’t know everything in category (2) on the list, maybe there are some sites on it whose suitability is more debatable or mixed, and its inappropriateness may be less obvious to someone than Breitbart’s (hopefully) is
