That’s not my forum to moderate so I don’t know where lines are typically drawn there, but here’s my thoughts on it.
Your OP with the “Please do not attack the posters who admit this, guys” is, in my opinion, perfectly fine. It’s your attempted enforcement of that later in the thread that very much comes off as junior modding.
This is VERY CLEARLY telling them what they are allowed and not allowed to do. This is where you not only went over the line, you went zooming waaaayyyyy past the line and kept on going. This one’s not even close. This is practically the very definition of junior modding.
