I think as a manager you can't erase this blame fully where its a matter of your own reputation too. Every manager should think about investor safety first before taking a project. I believe well reputated managers have the quality to investigate a project and after deep investigation they can easily detect that projects future value. Just taking a project only for having payments and after revealing scam accusation against that just locking ANN thread can't be a proper solution man. It was very much needed to be careful before making the ANN. You have to bear it on mind that already so many investor have been connected with that existing project.

IMO its a complete carelessness about investors safety where as a manager its your first responsibility to make sure existing project investors safety first.
