Hi, original banning staff member here, I watched the altercation happen live where an apparent RDM bait incident occurred, a member of your faction stepped onto the roof of La Volpe and refused to leave until he was punched, as soon as he was you proceeded to spray down those who hit him and anyone that started to shoot back at you, Your positioning on a rooftop and the fact your friend went up to them as soon as you were in position made us believe this was pre-meditated..
To address why the others received a note- They were already on the roof for about 10 minutes prior to this, Yumeko's note was removed as she did not shoot anyone and arty received one for participating as he should have known better.
I believe you deserve to be banned as you should know better from your many staff sits and time on the server. However, I do believe a perm is excessive given the circumstances of hostility in the city, with many shootouts happening and lines being unclear. However, I do think the original 30-day ban would be appropriate given your priors + circumstances.
