Why the fuck do u care for that letter?!?!?!?! YOU ARE THE FANS, THEY DEPEND ON YOU TO MAKE MONEY!!!!! LEARN IT ALREADY!!!!! FUCK SQUARE ENIX. U have to tell them "we will continue and if u threaten us again we'll boycot u" (a simpley hack VS lots of money)
Anyway, you still have a way to continue with Crimson Echoes,
1) Fisrt u say "well ok we'll shut everything down, so to wash your hands (lavarse las manos por si no se entiende) and later say we don't have anything to do with it
2) MOVE THE PROYECT TO TOR (The Onion Router,
www.torproject.org ) so u'll stay anonymous (they can't soe the air), put up a hidden service and there u have your project totaly protected
3) Say u don't know anything about it, or who is behind it, that apparently, someone continued from a leak or something
4) If you are going to do it, at least delet this post so they don't suspect (or delete the second paragraph)
Well, i hope u SAVE the project, and fight back. Just like TPB is fighting agains the riaa, mpaa and others.
