The First Amendment's guarantee of free speech is subject to several limitations. Speech that incites violence or imminent lawless action, defamation (false statements harming reputation), obscenity, 'fighting words' (likely to provoke immediate violence), and true threats are not protected. Commercial speech, particularly false or misleading advertising, can also be regulated. Courts also have recognised the need to balance free speech against national security, public safety, and individual privacy. CAN-SPAM is constitutional because it regulates conduct (requiring identification) not content. While the First Amendment protects against government censorship, private entities can still impose consequences for speech.

The First Amendment, while guaranteeing freedom of speech, is not absolute. Several categories of speech receive less or no protection. These include speech that incites imminent lawless action, defamation (false statements harming reputation), obscenity, 'fighting words' (words likely to provoke immediate violence), and speech integral to criminal conduct. Commercial speech, especially false or misleading advertising, can also be regulated. Furthermore, free speech rights must be balanced against other important interests like national security, public safety, and individual privacy. While the First Amendment protects against government censorship, it does not shield individuals from the consequences of their speech imposed by private entities.
