What they need is to have two options: A green thumbs up or a yellow exclamation mark, or whatever, but nothing in-between. To retain the green icon, the TA would have to verify the count every 30 days, PERIOD! If it goes past 30 days, OR if somebody other than the TA changes the count (even if by mistake), it becomes the yellow icon. If they were to implement this immediately, that could help get more TAs and companies on board. The shareholders would start pushing for the 'verified' icon just like they currently push for the current status.
Sure, they would still have enough time to dump a few trillion shares between updates, but at least potential shareholders would have an idea where they were starting from. And if daily volume is double the 'verified' number they can pretty much guarantee it is being diluted.
