What would I do if my board was leaked or copied

[Kuro The Dark Angel]

I am a helper for a developer of a roblox game, alot of roblox developers are using this platform now to help organize their game and give out information about their game. However, the board we used for private matters was leaked by an unknown user. Is there anyway I can ask a Trello Moderator to delete this board?

You'll need to ask the owner (admin) of the Trello board to kill it off.

I have tried to do this, however when I contacted them. They shut me off immediately and gave no further response. I can no longer contact the person responsible and I do not think they plan to delete it
