Too be fairly honest here.
The thought of being in a dangerzone of being penalized is far greater than knowing you're in a dangerzone of being penalized.
In a way of saying it, let's look at it like fotball. The **yellow card **is your 14 days ban, the red card is your 'pack your bags and leave' ban. If you mess up you deserve instant action ( in this case~penality). If I decide to do something that's not allowed I should not have a warning "listen here, since its your first time its okay, next time its not. I'll have to pull up the yellow card on you soon".
In short; having such lets you controll your risk of penalizing & im sure the majority does not support that. How? Just because.
Sadly no support from me, but i respect your thoughts! :)
