Why system reject me?

As you can imagine, we look at a variety of factors in making this decision, and we're not able to disclose specifics to protect the integrity of our methods and systems. If you signed up for an account and it was canceled, we ask that you send an email to support@linode.com that includes the last 6 digits of the payment card used as well as the username/email address. Please include any other information that you feel would be helpful to us when reviewing. Once that is received the team can take another look at the sign-up. If the decision is made to activate your account, you will receive an email advising you of this. If you do not receive a reply, this means the decision to cancel the account could not be overturned.
