ORDER AND JUDGMENT *
Carolyn Ann Bell, a federal prisoner proceeding pro se,1 appeals from the district court’s denial of her motion for reduction of sentence brought under 18 U.S.C. § 3582(c)(2). History reveals her persistence in attempting to assert rights to which she is not entitled or clearly waived in her plea agreement.
Pursuant to a plea agreement, Bell pled guilty to possession with intent to distribute fifty or more grams of cocaine base or crack. Since she was a career offender, she was sentenced to 262 months of imprisonment and a five-year term of supervised release.2 Despite having agreed not to appeal, she did. We dismissed her direct appeal based on the waiver of appeal rights contained in her plea agreement. United States v. Bell, 343 Fed.Appx. 376, 377 (10th Cir.2009). Later, and despite her agreement not to do so, she filed a motion under 28 U.S.C. § 2255 collaterally *845attacking the sentence. The district court denied her motion. She appealed and sought a Certifícate of Appealability (“COA”). We denied a COA; again because of the waivers contained in her plea agreement. United States v. Bell, 437 Fed.Appx. 658, 665 (10th Cir.2011).3
In 2010, Congress enacted the Fair Sentencing Act of 2010 (“FSA”), Pub.L. 111-220, 124 Stat. 2372 (2010). Among other things, it significantly reduces the sentencing disparity between crack and powder cocaine. Later in 2010, as required by the FSA, the Sentencing Commission amended the Sentencing Guidelines to reflect the change. See U.S.S.G. § 2Dl.l(c) (2010). In her § 3582(c)(2) motion, Bell claims to be eligible for what would amount to a retroactive sentence reduction because of the change to the guideline.4 The district court denied her motion. She renews her arguments in this, her third appeal, but they are untenable for at least three reasons.
First, her plea agreement specifically precludes her not only from collaterally attacking her sentence under § 2255 but also from seeking to modify it under § 3582(c)(2). See supra note 3. Our previous analysis of Bell’s plea-agreement waiver of her § 2255 rights applies with equal force to preclude relief on her § 3582(c)(2) motion. See Bell, 437 Fed.Appx. at 661-64.
Second, the FSA does not apply retroactively to individuals sentenced before it became effective, August 3, 2010. Dorsey v. United States, — U.S.-, 132 S.Ct. 2321, 2335-36, 183 L.Ed.2d 250 (2012); United States v. Lewis, 625 F.3d 1224, 1228 (10th Cir.2010), cert. denied, — U.S. -, 131 S.Ct. 1790, 179 L.Ed.2d 660 (2011). Bell’s crimes were committed in 2008, and she was sentenced in 2009. In addition, the Sentencing Commission’s implementing the FSA with retroactive Amendment 750, effective November 1, 2011, does not help Bell because she is a career offender.
Third, Bell’s arguments regarding the guideline changes now reflected in U.S.S.G. § 2Dl.l(c) misapprehend the significance of the career-offender guideline, U.S.S.G. § 4B1.1. “Under the policy statement, a sentence reduction is not authorized if the amendment at issue ‘does not have the effect of lowering the defendant’s applicable guideline range.’ ” United States *846v. Corber, 596 F.3d 763, 766 (10th Cir.2010) (quoting U.S.S.G. § lB1.10(a)(2)(B)), cert. denied, — U.S.-, 131 S.Ct. 897, 178 L.Ed.2d 746 (2011). In Corber, we affirmed the district court’s denial of the defendant’s § 3582(c)(2) motion based on the subsequent sentence reduction for crack cocaine, because the defendant was a career offender; “the district court had no authority to reduce the sentence.” Id. Concerning Bell’s career-offender status, the district court noted: “Her conviction in this case, based on conduct that occurred in November, 2008, was her fourth conviction for criminal conduct relating to distribution of cocaine or crack cocaine.” (R. Vol. 1 at 17.) Because Bell is a career offender, her sentence would not change even if a sentence reduction for her crack cocaine crime were possible, which it clearly is not.
Bell claims the district court had discretion to reduce her sentence. As we have explained, she is wrong. She also claims judicial bias in not granting her § 3582(c)(2) motion. Her arguments regarding that claim are contrived and insulting, the last refuge of the truly desperate. We will not dignify them with further discussion. In any event, they matter not because the court had no authority to grant the relief she seeks.
This is the fourth time Bell has filed motions with the district court contrary to the terms of her plea agreement and the third appeal she has brought contrary to that agreement. Enough is enough. Further motions and appeals may well result in filing restrictions or other sanctions.
We deny Bell’s motion to appoint counsel on appeal and all of her other motions that may remain unresolved.
AFFIRMED.
