Unfortunately, we can not do much about this. The only thing we can do is not to participate in such projects and without our funding, no one will survive. I do not know how to remove them, but we really need to do something about this, otherwise it will continue to grow. Now what we can do is just to avoid them, study about their groups and projects before you join any ICO.
You can do much, convincing a project scam or legit project is not as easy as you might think. You cannot be sure by just looking at the developer but there are many small things that can ensure that the project is scam or legit. You can be active in scam accousation forums in order to ensure the project, the more people who understand or know how to convince a project, the more chances of cryptocurrency avoiding a bad image scam.
