How do you politely request the “no hello”?

I truly TRULY loathe when a co-worker sends me a Teams message “Hi Amanda!” And then waits until I respond back to ask their question or make their request. Even when I respond immediately, it sometimes takes up to an hour for them to respond back.

I am a “no hello” person. (Check out nohello.net for an explanation). I do not want to be rude but I’m also almost to the point where I am going to start ignoring people until they message me what they need. How would you request that people stop with the “hi” messages?

Edited to add: NoHello doesn’t mean you don’t say hello and just launch into your request. It means you don’t just say “hello/hi” without any context when you have a request/question. NO, I do not just send people requests/questions, I say “Hi [person]! I have a quick question regarding the financials in your recent report. Is there a good time to talk about that today?” That is all I’m asking for. I’m not telling people not to say hello… just combine your ask in the same message so I know what we’re getting into and can prioritize it appropriately.
