One revealed scam produces 5 new scams, of course that nobody can do anything about that. What we can do is to protect ourselves as we know, education and learning can help in that, other than that we can sound an alarm in scam accusation section and to hope that others will see it.
One huge problem about scams and accusing services and projects to be a scam is that sometimes some good projects get targeted by the scammers. I am not sure is there one coin or one service that hasn't been accused of scam at some point, we still have people who speak about bitcoin as a scam, what to say more?! So be careful about projects that are tagged, but in the end do your research, it's not a scam just because some people yelling it is.
