After looking at the evidence I've decided to accept L3mons report. However, after looking at their rap sheet they have a clean sheet. I've made the decision to leave it to a verbal.
L3mon shouldn't have killed you for no reason, but I believe you could've avoided the situation by not constantly coming back. Also, you didn't lose anything but only 3 footsteps from spawn.
I can understand if he was annoying you, but I advise you to try your best to avoid the people annoying you so we can help you as best as possible instead of trying to provoke people.
Consider this,
