(1) The circumstances under which hyperlinking to material posted and hosted by others is, or should be, a crime.
(2) If it is a crime, whether the proposed sentence is proportional to the alleged offense.
(3) Whether the prosecutor is trying to exert pressure for a plea bargain. E.g., if they offer him 100 days in jail if he pleads guilty, or 100 years in jail if he's convicted, it would make sense to plead guilty from a pure risk management perspective, even if he has an enormously strong case.
(4) If this length of sentence for this behavior is authorized by statute, whether the statute falls foul of the Constitution's prohibition of cruel and unusual punishment.
(5) Whether the First Amendment protects hyperlinks to unprotected speech.
