IDK... I would think all one would need to do is change the Admin password so that JC couldn't make any changes or updates.  Seems to me the CEO of the company which owns all of the assets (I assume including the website) could simply call the domain host and have the password changed.  Boom... done... no more nonsense.  There would be no need to remove it from view.

Perhaps it is just a server problem at the site hosting service, I guess that's possible.  Maybe it will come back on line soon.

This is why silence is NOT golden.  If we had communication from the company... speculation would not be necessary !
