Suffocation death in plots

[krotenkoker]

I walked through iiDamiaanPvP their plot when I suddenly started to suffocate in non-existent blocks, in a panic I logged out but when I logged back in I was dead and all of my stuff was gone. My brother made it happen a second time and filmed it. I lost all the stuff I had on me at the time: A diamond pickaxe with efficiency 3 and unbreaking 3 I also lost about 26 XP levels
here is a youtube link to the video:

when I walk in now it said entry denied, I think iiDamianPvP closed his plot to kill me the fact that he did it twice makes me believe that he purposely tries to kill people with this trick.
