Pplzofdaworld griefed Me and Devans City.

Devan bought flat land off of Spxify and placed signs around it saying it was his but Pplzofdaworld apparently did not see this sign and griefed/built on the land.
We would like to ask that he be warned/banned and rollback'd.
Here are screenshots

Spoiler:

The coordinates are:
X:-59
Y:73
Z:-2881

Signs noting ownership were placed on 1st September, house built on 26th August.

That Spxify tricked you!

I indeed sold the 200x200 area to devan. Devan claims that there were two signs originally on the 200x200 area.

EDIT: Devan placed a pile of wood/logs next to the sign which were placed long before.
