Nostalrius Begins - Quality wow vanilla realm (1.12)

So as the event i was doing has started yesterday, guard thomas was in the wanted list, therefore he was killed constantly till alliance 60s defended and big world pvp happened blah blah..

He was killed for about an hour or two. Then we fought in some other spots of elwynn.

Anyway, on our 2nd invasion, after some invaders started killing him, 15 minutes later they got tped to that bizarre gm interrogation room, and were told to stop or get banned

I though the rule said constant killing npc for more than 24 hours continiously? Even though, 1 time it lasted for an hour, the next day, they got warned after 15 minutes.

Are the rules changed? If yes, please do clarify. Alliance was there to retaliate after all.

seems that some of these new gms dont really know what they are doing so it could have been a mistake

GMs always side with the "victim" in situations like this, it's pretty pathetic.
I once got warned and was put on a "GM watchlist" for killing someone who was streaming because he was under some weird impression that streamsniping was against the rules.
It got revoked 30 mins later when a spoke with a less clueless GM, but by that time I was back in Orgrimmar.
