Hacker teleported to middle of nowhere

[vanslyke 1]

I know I've seen this issue talked about before but i didn't see a fix and it hadn't happened to me at the time. I was playing the game alone and all of a sudden some guy appeared next to me. i was teleported into the sky and started falling so i quickly aborted and joined a different server and i was in the middle of nowhere and can't suicide so I'm stuck. any fixes any help would be greatly appreciated
