Griefed and put locked chest with his name on it [Pops] [Lack of proof]

I would like to report danger1324 because he griefed my small platform I created and claimed it was from his friend he tp'ed to my platform. When I asked him who, he said "someone", when I asked again, this time in all caps, he said "my friend". He also went around breaking all the chests and spawner he could on the platform, and around me. Finally, he put a chest, locked with his name on it, on the platform without my permition, and then left without letting me consult him about it. Now it is, as I know, still there on my platform, and its quite annoying.
Once again, the player is danger1324, and please stop him from doing this again
to another player, and going through the annoyance I did. Thank You, your new member, SoulEater859

 

Evidence?

 

Let me update you on this, he also stoll EVERYTHING in my chests. I had quite a bit of work and effort put into everything I did and put it in my chests. now its all gone. :'(

 

No, sadly I didn't think of taking screenshots but I just went on and took a screenshot of the grief, here :

 

Griefing is allowed on skygrid, unless the land was protected with sponges. Can you provide proof of sponges being placed?

 

24 hours to provide more proof.

 

no, i guess it was my (put inappropriate word here) fault, but the least you could do is replace the stolen items, but no, im done here

 

Closing due to lack of proof. I'll give you some items if I see you on.
