How do Americans buy tokens when it's illegal to do so?

I'm new to the world of ICO's. I think I came across a good one by TipBlockchain. But they dont allow residents of US and Canada to participate in their token sale, which is very disappointing (plz see attached screen shot as proof). How do Americans and Canadiens get around the blockade? via /r/icocrypto https://ift.tt/2L1Ijg0
