Im sure competition for customers is heavy and hack is main weapon for sabotage but what make me suspicious is forum post deleted. If they are under attack and want to keep his customers calm its not hard to make few updates here and set new blog for keep us up to date till all is fix.
Right now its don't look good.
It is the most normal thing to do. But they has been hacked (if true) and they are shocked. Maybe this can justify them.
