i can see what your saying, but the defensive line is 10mtr back. Using this tactic is just encouraging the hooker to run at you an get over the advantage line with ease. The first market must put pressure on the hooker, he doesn't have to run after him like a headless chicken.

It's if you get over aggressive at marker and push too hard to get around the play the ball or start chasing other attackers that the space opens up. Just split your markers and hold position and the hooker can't gain more than two metres. If the opposition do that five times and make ten metres in a set of six, you'd be pretty happy.

I'd agree. I havent had a problem with the vast majority of penalties given against us, other than the fact that the teams we are playing appear to be holding down etc just as much without getting penalised.
