I'm pretty sure that "rule" was more aimed towards "just ask your question" rather than "greet, make smalltalk, then ask your question".

I have similar rules, though I don't communicate them as aggressively, and don't ban people for breaking them, I just don't reply to greetings coming from people I know aren't looking to talk to me to ask me how I've been. It's a lot easier if you send the question you have instead of sending "Hi, how are you?" and then wait for 3 minutes to type out your question.
