They suspended my account after I registered 21 domains at .99 each. They refunded everything and sent this email:
Dear Valued Customer,

As part of our efforts to vigorously protect our customers against on-line identity theft, the transaction has been flagged and identified as high risk by Risk Management qualifiers.
Register.com takes this matter very seriously. We have credited the charges in the full amount of $20.79. In addition we have deleted the services associated with the above transaction.
We apologize for any inconvenience this may cause. If you have any further questions, please reply to this email or contact a Customer Support representative 24 hours a day, 7 days a week, at the numbers below.
