Peter J. Biondi, NJ Assemblyman for District 16, has introduced A1327, a bill to force every ISP and website with comments/forums to demand user identification from every single poster (called an "information content provider" in the bill). The bill also forces all ISP and websites to turn over that information upon demand to anyone who claims to have been defamed, without any legal process or protections:

Well, it appears Seigenthaler's stupid campaign to remove due process protecting the identity of Internet posters, based on the inane assumption that claimants are always good guys who always have a legitimate claim, has gotten traction in the New Jersey legislature. MemeStreams users in New Jersey ought to contact their local representatives and calmly and respectfully explain that for every human problem there is a solution that is simple, neat and wrong.

Talking points:
1. Anonymous and pseudononymous speech has a long history of political significance in our country.
2. People seeking to identify Internet users do not always have a legitimate claim. Sometimes they are stalkers or other criminals.
3. Having a court decide whether Internet Services are required to turn over personal information about their customers creates a process which validates the legitimacy of a claim before personal information is forcibly disclosed.
4. Internet message boards are often informal things run by hobbyists. Information collection and reporting requirements create barriers to entry for those seeking to operate message boards, which has a deleterious effect on the free flow of discourse critical to our democracy.
