I just got the following E-mail from Mediafire:

However, they placed another strike against my account yesterday morning, this time for a file named “Super Secret Santa Build Mode” . The file was also removed.
Hopefully, this situation will end with this e-mail.
Update: The files have been recovered and re-uploaded thanks to the awesome people at Tumblr! :)
