Just like vugto said in the begining of the thread. If you kill some one and the other person is resurecting again and attackes you, i think you should be allowed to attack him and kill him again. If he dosent attack you, you can count that as spawnkilling the next time you kill him.
Yesterday i got banned for attaking some one that killed me. I resurected and then an other mage killed this guy and then after he revived i killed him once, then i got dc's and banned XD
And it really bothers me the gm's have to watch you spawnkill or "GET" spawnkilled*..
