One disposable SIM card is cheap. In Romania it's about $5, coming with initial credit on it as well. But multiply by 1000 and then you're talking about $5000 versus zero, plus the hassle of verifying each of those accounts.
And because it has been a practice to sell cheap calls by VoIP services piggybacking on special offers for PrePay SIM cards, the GSM operators now have protections of their own, so it will be expensive to automate this.
