Explanation of the trade: I might not be able to give proof completely because they just deleted their server without any prior info. I was working with them for a year approximately. 14b+ earned as a service provided there. Left the server in January, and they added our December payments in some 'wallet 2'. But never paid that I owed there 390m. My worker role was taken off so I couldn't take screenshots of that. I just took like 2-3 screenshots unintentionally. Never thought they would do this.
LD wasn't answering the ticket I have texted him personally but he keeps on ignoring me.

DDRSR is saying he has transferred the ownership but LD was running the server with his name, with the same profile pic on his server. His name was used on the server. If something happened to whom we can ask, I don't even know if LD has any sythe or not.
