I am already wrong since I am replying to an AI blog post - but -

The point of these is that it is a widespread annoyance. No, it's not nice to send someone a link to nohello.net, but it is letting them know that you are annoyed.

If every time someone Slacks you "Hello", you send this link, you're probably an asshole. If you send this to your boss, or to senior people in your org, you are a moron.

But everyone knows the serial "hello"-ers, and if you tell them nicely "Please just ask your question", they will just say "Yes of course", and then do the exact same thing next time. By sending the link, you are telling them, YOU ARE ANNOYING ME, without having to be so direct as saying something like, "If you Slack "hello" to me while I'm working outside of my hours on a customer deliverable one more time I will lose it with you".

It _is_ a shaming. It _is_ a talking down to. It is saying "get a clue".

But I have slack conversations that are just "Hello" - "Hello" (weeks pass) "Hello" - "Hi" (days pass) "Hello" - "Hi".

They do not have a specific question for you. They are looking for someone to dump their work on, and they pick whoever lets them know they are available, by replying
