i do not like "lighting " someone up unless its a really bad situation, i've only done it twice or three times in all my years of playing, but i will tag him once a second time if i see him wipe, then in a calm manner tell him he's out.
Yelling at the person or swearing at him only antagonizes the situation, most will leave if you inform them in a nice way that you witnissed the hit, and they should leave
