Any organization would also not hire back a person who demonstrates the same pattern of behavior time and time again, shows no progress in trying to learn from past mistakes , own up to them and better himself. He has also disrespected the krew and many people who gave him chances time and time again, not even having the courtesy to make a post. At the very least Tito made a post, came clean and took the heat.
Stevo also needlessly inflamed the whole situation because he was pissed off by posting those chat logs. In a court room, a judge would have thrown out that evidence as highly inflammatory and proof of nothing.
