I have a negative feeling about this, it gives me that "self centered jerk" vibe... no, I will definitely not let people wait just to "teach them a lesson" then rationalizing it "I'm doing it for their own good". If I cannot answer I say "sorry no idea", if I can answer I answer when I have time - and that will happen when I can make time. And if it's really burning they'll ping me again and I'll see what I can do then.
