So your saying if someone tried to hijack micsoft or IBM they would take the same action - and turn it to a grey without any MMs trading . Ye right.
The bottom line the brokers and MMs who have profited from selling these shares in the market also get off with it scot free - why shouldn't they have to pay back the profits/margins they have made in trading illegal shares.
The SEC have allowed these scams to run their course for decades and have done nothing to prevent it. When you have a system that can be easily abused then it will.
