The fact that Usagi evidently deleted hundreds of post would imply wrong doing.  IRL that is call destruction of evidence.  

Usagi,  I would suggest you restore those post or allow admins to restore or release.

In the mean time does anyone have a gpg signed contract that usagi broke or failed to honor.

Does anyone have screen shots or copies of the posts that got deleted.  

Maybe you could get MOE-PR or JoelKatz to argue your case, but with out hard proof I'm not sure what admins can do.
