A federal judge called a Louisiana law, banning certain sex offenders from Facebook and other social networking sites a “constitutionally problematic” statute. However, he did not decide Wednesday whether to throw out the embargo, which took the result in August.

U.S. District Judge Brian Jackson, based in Baton Rouge, heard arguments from a lawyer, which represents two convicted sex offenders who seeks in overturning the law, and from the attorney general’s office that defends the statute.
