Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello GMs, about 30 minutes ago i was leveling my warrior Lylah. I instantly died while walking down a small hill. I thought it was buggy fall damage, but the combat log just showed "You died". I was rezzed some seconds later, ran like 4 meters then died again. After this i spawned at the graveyard, my grave right next to it (altough I died quite far away from the yard) and rezzed. I looked around and was suddenly disconnected and can't log in again since. Have I violated any rule and if so, what was i doing wrong? Or was this a GM being funny?

I'm sorry for the typo, ist Lysah on the PvP realm.

Hello Benevael,
is there a way that I can prove to you that I was in fact playing my warrior? The only thing "automated" is a overpower macro which I found in this forum. Do I have to change my play style in order to play on this server?
Don't take this the wrong way, I know you're doing your job, but I simply don't understand what I should have done differently.

Thanks for taking the time to clear this up.
