Yes, these fake developers should be held accountable. Unfortunately I've seen many projects recently where there is a nice proposal, the devs ask you to invest, but don't do what they promised afterwords and only collect the money. That is just fraud, but for now they seem to get away with it. I hope these practices will be addressed. Not only by bitcointalk but also by law enforcement agencies. This will be beneficial for the sector imho. I lost some money with AMMO unfortunately and by more enforcement the risk of being scammed may be reduced a little.
