When there are limits people wants to buy more. Then to sell tokens afer ICO for a good price. A good business. Some people buy tokens only to resell them later for speculations.
I saw someone even trying to sell their seats in white lists of projects. Funny business, but it becomes relevant because of limitations of participation in ICO for citizens of some countries.
But such way creates an agiotage. But here is obligatory verification, so if you are a resident of the country where the ICO is prohibited, then you just will not pass the verification.
Therefore, the one who sells his place in the white дшыt passes the test. I do not know exactly, because I do not like such schemes, but most likely it is. I can understand people from countries where participation in ICO is prohibited. Everyone wants to make money and, in principle, be economically free.
