I would turn this around and call this a product design problem. Maybe Slack shouldn't send a notification when all you've said is "hey" and you're typing a follow-up message.

Really, if you have to publish a blog post explaining to people that they're using your product wrong, I'd say your product needs work.

Teaching people to replace "<send>" with ", " is better than trying to design a filter for every salutation.

Not every social problem needs to have a tech solution. Slack allows sending messages between people. They don't need to start policing the content of these messages.
