SEC will eliminate the ico which has gained money from US investors. They will not even care about what will happen with investors from another country. Most of icos don't even know what is blockchain and how to research its potential. Basically they are creating their own idea based on their imagination.
SEC cannot help much the people from outside US. Fraudulent ICOs will keep getting created.
We (as community) will have to learn to not just jump in, we will have to learn to try to understand what's an ICO about and if it has a fair chance to give profit.
While many give a lot of good advises about what to check for in an ICO, I am certain that many don't understand those things and just go with the flow, because, "you know, others have invested too". And this can be a trap, because in the same way nobody should get investment advises from unknown people (and they still do), they should also not believe every account, because they can be honest, but they can also be just the sock puppets of the scammers, or also people that have fallen for the scam and they don't know it yet.
Then the numbers. The official numbers about how much money was collected may be or may not be for real.
All in all, please try to learn and use your own judgement. If you just don't know, better try to stay closer to the safe side...
