The bill is considered controversial because according to its critics the bill could limit access to a wide range of websites, including many with harmless and educational material. Arguments for the bill focus on the fear of adults contacting children on MySpace and similar websites. Many Internet websites, however (ranging from Yahoo to Slashdot to Amazon.com), allow user accounts, public profiles, and user forums, in accord with the bill's definition of "social networking". The bill places the onus upon the Federal Communications Commission to provide clarification.
