Your screenshot shows an SQL DB, so I still do not know what you are looking at there, it certainly isn't real blockchain data.
If you are implying that someone deleted something from some database, you should be more specific.
Deleting evidence on the blockchain should by no means be possible!
Also, that "owner" thing you are highlighting contains child elements, you are highlighting the parent level and it's properties, not the content. Even if someone deleted the contents here, the owner signature of the account would be gone, making the account invalid. so yeah?!? What is this even supposed to be about?
What "side" is that you put me on?!
