Grief In Creative WTF?

So On December 5 2013 I was derping along in my head shop in creative, there was some ppl on my plot, and then one wall turned into water then the other wall turned into lava and my shop turned into water/dirt/lava/obsidian there was alav all over meh plot and the plots around me were also affected by it. Only World Edit could of done this.
People added on my plot: Jurubasbas, gabiku, EpicDudeMC.
Please Roll This Back I Dont know who or how they could have done this, Maybe Hacked Client?, but please help images are below.

How do they even get access to your plot(s) if you don't even invite them? .-.

 

Hackers @so2315

 

This has happened to a lot of people, and should come to an admins attention as it is serious.

OFF topic: Lol this happened on my Birthday and nice profile pic

 

The people used world edit too on my plot and I got griefed.

That's why I removed all the staff in my plot.

 

Clear your plot and restart all over again and I'll help you with your plot.
