pre-Iqbal/Twombly, that circuit “set forth a liberal interpretation of Rule 9(b)” that may have permitted the type of pleading plaintiffs offer here. Swanson v. Wabash, Inc., 577 F.Supp. 1308, 1321 (N.D.Ill. 1983). Given the contrary authority discussed above, and the strength of Rule 9(b)’s requirements, the court finds plaintiffs’ authorities unpersuasive. Consequently, plaintiffs’ RICO allegations fail on this basis as well. 5. Plaintiffs’ RICO Conspiracy Claim As plaintiffs have failed to allege an underlying RICO violation, their conspiracy claim under 18 U.S.C. § 1962(d) fails. Because plaintiffs have not adequately pled a substantive violation under § 1962(c), they cannot allege a conspiracy to violate RICO. See Sanford v. Member-Works, Inc., 625 F.3d 550, 559 (9th Cir. 2010) (<HOLDING>); Howard v. America Online Inc., 208 F.3d 741,
