Yeah. A key concern that people have had with quadratic funding and with quadratic voting is that, as you were saying, people can register with an SMS. So as long as they have a SIM card, then they can potentially get a bunch more votes. And so in this case, obviously someone could sign up with a whole lot of SIM cards. And in other cases, you could potentially get an advantage by basically convincing a friend to spend some of your credit — basically coordinating in order to pretend to have more spread-out preferences than you actually do.
