The internet has no governing body through which laws and policies are enforced. The responsbility for safefy and security on the Internet rests with those who use it.
Communications Decency Acts (CDA), Feb. 8 ,1996
In July, 1997, the US Supreme Court ruled 7-2 that the CDA was a violation of the First Amendment and thus unconstitutional.
Common sense dictates some basic rules of conduct.
