No offense, but that's a pretty weak argument. I could name you a quite a few companies that are obvious scams that didn't get suspended on Tuesday. The SEC isn't going to shut down every company that puts out false and misleading information or does stuff that is illegal. They just don't have the manpower or the resources to keep up with them all. Typically they tend to spend more time on the companies with the higher market caps because that just makes more sense economically.
The SEC cannot hold every investors hand and protect them from every company that is putting out false information to support some kind of share selling scheme.
Investors have to have some level of responsibility for the POS companies they decide to invest in. Some fall for the hype and then lose and learn from their mistakes. Some never learn.
