To preface, I was the member of staff who handled this sit.
RNJesus and Thin were taunting and bickering in OOC for roughly two hours prior to the sit being made, with this context I did not see fit to formally warn either of them for player disrespect or toxicity as I felt RNJesus had an equal hand in how this event unfolded. I issued both players verbals to simmer down in OOC, a verbal for the NLR break as in the worst case (27 seconds) Thin did not engage in combat for 3 minutes after entering upper D-Block.
Throughout the duration of the 20 minute sit, you were extremely eager to see Thin warned, even going as far to state "I am A-OK with being warned if he gets warned too". To quote the rulebook "Retaliating against a player that is engaging in toxic behavior does not excuse your own behavior" and in a case like this I would much rather players settle their differences than issue formal warns to both.
