I know it would be nice to have a little bit more information from him regarding what's going on, but what will harassing him achieve? Is he not aware that people want to know what's going on?
I am not really sure that people contacting someone who has their money and has CHOSEN to remain mute about what he is doing with their money would be considered "harassment".
Even if he was being advised by lawyers, he would have made a more professional statement with information by now. This stinks and sounds more like the reaction of a teenager to trouble than a business person.
