My "Friend" just destroyed and get all items and left the game and not going back the island got destroyed 5 min ago so much of my hard work destroyed i will be happy if any staff could help
if it was your "friend" he/she was probely trusted. that makes it a player vs player issu and staff will not interfer

If you trusted them, then I trust your judgement on whomever you trust on your island and therefore wouldn't intercede.
I've looked at the island in question, and it appears that you are a member on someone else's island with an owner and other trusted members. Since I don't see anything obviously damaged I'd suggest you at least tell me who you think damaged the island and where.
