I have been known to stamp as hard as I can on a repeat offenders ball, sinking it quite some way into the fairway, then watch them try and dig it out with a wedge! Numpties. :thup:
Why would they try hacking it out? If they saw you do it, then they could replace the ball in its original position (or near as). If they did not see you do it, then they could assume it was plugged it its own pitch mark and take relief.
Nah. There's better ways of getting revenge.
