Just because you're on the recieving end of the hand of justice doesn't change your opinion into fact. (Odin's Book of Proverbs (noteworthy of being the home of the immortal 'It's easier to judge others when behind a leather chair."))

Anyway, I believe that after a while, warnings/subwarnings should dissolve, the time it takes to do so depends on the severity of the warning. However, I think this system is already put into practice.
