I need help!

This player Bad_Girl15 has been spawn-killing me for a while now and I couldn't move 2 blocks without dieing. She is destroying everything I have. She also just said that she is a hacker. I was just able to teleport to spawn. I can't go back to my house.

She's not a hacker. That's Bluedragon's sister. Or her account at least...

All I know is, that the person on the account said they had a client side thing helping them hack.
I should probably say I was in anarchy 3 while I was being spawn killed, I would die in not even almost instantaneously. So I was trapped, rendered unable to play for at least 7 or more minutes. That's why I came here. I know Anarchy has few rules, but when you can make it literally impossible for someone to play on that server, and have no worries, it's kinda bullcrap. (No disrespect)
