my discord server were stolen

Hello, my 100k discord server has been stolen! I tried many ways to compromise with the hacker to regain access to my server. My Discord tokens were leaked when I attempted to make a bot for my own server, and the person who "hacked" my account transferred ownership to himself. I wondered if you could help me to regain control of my own server. I have all the evidence that I am the owner. The hacker is attempting to sell the server for 500 dollars. Furthermore, he scammed someone 140 dollars from selling ownership of my server and didn't give it to the buyer. I really wish for help 

Further more story 
As usual, I woke up and decided to check my discord server to see all my staff were being demoted. I also saw ownership of my server was being transferred to someone I didn't even know, who said he would return the server ownership if I gave him a nude photo of one of my staff, which I did not supply him with. His goal was to scam more people by placing ads for his token grabber in order to get people to click on the links which he openly said it in my chat. (He deleted most of the chat some of the chat were already screenshot)
