If someone sends me just “Hi” in slack, they’re still waiting to this day.

you should check out https://www.nohello.com/ Some folks at my workplace have been using this to explain their point of view to people who just send Hi/Hello

Or "Hey, quick question."

Ask the damn question then.

These "slack farts" really irk me. The first time someone does it, I usually respond with the nohello.com link and a brief note letting them know that the niceties aren't necessary - you can just ask your question.
