May debtors let stand a state-court money judgment against them, waiving the right to dispute postjudgment collection costs, and then challenge those costs in federal court as violations of the Fair Debt Collection Practices Act when the Rooker-Feldman doctrine bars such suits as de facto appeals from state-court judgments?

QUESTION(S) PRESENTED 1. May debtors let stand a state-court money judgment against them, waiving the right to dispute postjudgment collection costs, and then challenge those costs in federal court as violations of the Fair Debt Collection Practices Act when the Rooker-Feldman doctrine bars such suits as de facto appeals from state-court judgments? 2. Should the Court clarify when the RookerFeldman doctrine denies federal courts subject matter jurisdiction to hear suits implicating state-court judgments after Exxon Mobil Corp. v. Saudi Basic Industries Corp., 544 U.S. 280 (2005)?
