"Congress specifically enacted 47 U.S.C. § 230 (1996) to reverse the Prodigy findings and to provide for private blocking and screening of offensive material. § 230(c) states "that no provider or user of an interactive computer shall be treated as a publisher or speaker of any information provided by another information content provider," thereby providing forums immunity for statements provided by third parties."
47 U.S.C. § 230 (1996) basically covers online forums from being responsible for what other people post on those forums.
From what I can tell, it doesn't necessarily protect a person who uses one of those forums to post libelous claims, just because that person cites another source.
Arguably, the law could be read that way, but I would be surprised if the courts actually interpreted the immunity as broadly as you're describing it---that would pretty much gut libel law altogether. Do you have any case law to support your interpretation?
