This situation you are describing is not the reason for your Cophunt infraction
You were actually infracted for cophunting and killing me after we killed Clink and Rage. in Angel Pine Junkyard.
1- You had no active revenge on me
2- All suspects near us were dead when you attacked me (Both you and Arpa were innocent)
3- There is message proof of you telling Arpa "Let's go to Roro" which shows you didn't randomly run into me and try to help other criminals, you simply wanted to target me.
Why you didn't have revenge on me:
You were driving a car near many MWs and you started driveby shooting me, you damaged me, I killed you, 10 seconds later another player "Nicholas" killed me. According to the shared revenge rule - which you would know if you keep up with the rules, and you don't - your revenge was claimed by Nicholas because you damaged me within 2 minutes before my death, thus you contributed to my death and your revenge was claimed, any further killing would be considered RDM/Cophunt, however you did not seem to care, and still went for me.
"I didn't know" is not a valid excuse, rules are right there for you to read, and this rule is not even that new, it's been this way since October 26th and I quote Karbz:
3. If you contribute to the death of a player in ANY WAY that counts as your revenge claimed. ANY DAMAGE towards the player up to 2 minutes before their death counts as a ‘contribution’ to their death and your revenge on them is claimed.
A person like you with 11 infraction points is expected to be more careful when committing actions that might potentially be against the rules, and seeing your history of bans (you were banned for skipping animations literally last week) it seems like you haven't learned your lesson.
I personally would not give you a second chance, but I'll leave it to a higher staff member to decide.
