names that were subsequently indexed by search engines. Criticism Like other social networks such as Hi5, Names Database has been criticized for being too aggressive at encouraging registrants to refer friends. Upon registration the site immediately asks you to refer friends and then checks the validity of any address you enter, attempting to disallow fraudulent information. However, free access to searching the database is granted in the email confirmation without referring any friends, thus skipping that step. Also, all outgoing emails appear to follow the rules stipulated in the CAN-SPAM Act of 2003 including proper opt-out links, listed physical addresses and information about how the original email address was collected. Another area of criticism has been the expanded license granted to the site for information entered to it upon registration. However, this license is substantially similar or identical to that granted to other social networking services. Additionally, the site appears to try to collect only the minimal amount of information needed to find an old friend and classmate (name, birth year, email address and high school country with optional maiden name) as opposed to more invasive required information like gender, zip code and birth date as found on other sites. Classmates.com itself (the parent company) has been criticized for controversial business practices and legal issues, but it is unclear how much of this criticism also applies to their subsidiaries. In any case, The Names Database does provide the option of automatically removing one's listing in the database. However, these instructions have not worked since at least March 2013. Since July 2013 emails sent to the removal address bounce with a "mail transport unavailable" message. All requests for support through the website's form go unanswered, making it impossible now to be removed from the Names Database.
