How old do you have to be to join deviantART?

Currently deviantART's compliance with the Children's Online Privacy Protection Act (effective April 21st 2000) is limited to prohibiting any child under the age of 13 from opening, maintaining, or otherwise using a deviantART account. This restriction stands even when parental permission is granted.

"As we collect certain pieces of identifiable information and since a deviantART account allows a user to publicly display various types of personal and identifiable information (such as name, location and email information) we cannot allow children under the age of 13 to utilize an account at this point in time.

All accounts found to be used or maintained by a child under the age of 13 will be closed automatically and without notice when it is brought to the attention of the deviantART administration. Accounts closed in this fashion will be preserved until their user reaches the minimum required age of thirteen years old."
