I see no practical sense in collecting such data. We already know that there are a lot of cases of non-payment of earned tokens to us. And what will we do next with this information? The problem is that the ICO teams that deceived us are in different states, and many of them will not be established at all. We need states to begin to put things in order in this type of activity, since criminal fraud takes place here.
