Player x accuses player y for breaking NLR, the kills are pretty close together in console (a few lines apart) at a peak time.
I would tp Player y to me and ask: Why did you broke NLR? if he says: I didn't break NLR etc. i would warn him for Lying + Breaking NLR
Situation 2: If Player y says: What is NLR? first i would explain him NLR then i would warn him for NLR
