What we do is if we find some fact that may lead to a scam then we can report an accusation on Scam Accusation board so that we can spread it before they can even collected.
This is also the thing that we can do to help by reporting a scam Icos. By this way we can inform and help other investors not to put their money on the scam project. Also, we could have deligence on those Icos so we can avoid to be a victim of scam project.
