The U.S. House of Representatives voted 400 to 25 to approve the 118-page bill, which was the product of a compromise between House and Senate negotiators. The final version of the legislation bans erotic, computer-generated images that are "indistinguishable from" real children or teenagers and says that anyone who tries to lure an underage person to a sexually explicit site that is "harmful to minors" faces up to four years in prison.
