Didn't NRFL have sin bins a couple of years back?
Half the referees didn't use it which just caused inconsistencies and even more pressure with those who did.
The main issue with all these ideas is how they're enforced. It's often referees letting each other down.

1. Referees get together and ruthless enforce the rule which leads to a couple of weeks of farcical football with multiple sinbins until players learn or
2. The competitions ruthlessly enforce punishment after the game - which again leads to a few weeks of farcical football with players on suspension until players learn
