They also setup an LLC fairly early on, if I remember right - before they started publicly taking donations. Which, if I recall correctly, means that for them personally, there's now no more risk of loss to them. The worst that NCSoft could do is to tell them to shut down, and take all of the monies that HC has raised so far that haven't already been used. LLC protection (unless I'm mistaken) means that no member of the HC team is personally liable anymore, instead, it's the "Homecoming LLC company" that's liable, as if it was a person.
Which I think is BS, and a HUGE reason why so many things are going wrong in our society, but that's a whole different discussion.
