Registrars are not going to look and say "Hey, that name looks fishy..." they are going to say "okay, and your credit card number is...." People need to pay attention to what they are clicking on, especially in email. Granted I've mistyped a name here and there (common we are all human, right?) but if people stopped clicking on the misspellings, the scammers would just have to go find another way to get their "messages" out...
