Is it time to start calling out bad cyclists?

I did notice yesterday that when starting off I put a lot of pressure on the second (left) pedal stroke (as I'm already clipped in), and a rather ominous "crack!" noise was coming from the front end.

Hopefully I've not put sufficient force through the bars to crack the steerer, that truly would be dickish.

A tiny shift inside the headset, the thread moving against the nut, or the steerer angling back slightly under pressure can make a noise that resonates through the frame, sounding more worrying than it really is. I've heard nasty cracks from the front end on hitting potholes and on closer inspection everything was fine.
