ORDER

Moses Ramirez, who is jailed in Kane County, Illinois, filed a lawsuit raising a number of unrelated claims against the county sheriff and others under 42 U.S.C. § 1983. The district court dismissed that complaint without prejudice, telling Ramirez that he could separate his claims and bring them in distinct lawsuits.

Ramirez did so, and in this action he alleges that the codefendant in what appears to be a pending prosecution for selling cocaine, see Ramirez v. Illinois, No. 16-C-5420 (N.D. Ill. dismissed June 6, 2016) (discussing state prosecution), falsely testified against him in cahoots with the *823trial judge, the prosecutor, and even his own lawyer. Ramirez completed his complaint using a court-issued form, which ordered him (in all-caps boldface) to list “ALL lawsuits” that he had filed or risk dismissal of his case. Ramirez disclosed a single case, filed in Texas sometime around 2001, for which “all court papers have been destroyed” and the details of which he could no longer remember.

The district court took Ramirez at his word and granted leave to litigate the action without prepaying fees, see 28 U.S.C. § 1915(a), but then immediately dismissed the suit at screening, see 28 U.S.C. § 1915A.

A quick search, however, reveals Ramirez’s long history of frivolous litigation.1 Given that Ramirez already had accrued three “strikes” resulting from actions or appeals dismissed as frivolous or for failure to state a claim, he was barred under the Prison Litigation Reform Act from proceeding without prepayment of fees, see 28 U.S.C. § 1915(g). Yet not only did he rack up another strike when this complaint was dismissed, he deceived the district court and perpetrated a fraud on this court by falsely representing that he is eligible to proceed in forma pauperis. See Sloan v. Lesza, 181 F.3d 857, 858-59 (7th Cir. 1999).

A litigant who has accrued three strikes must alert the court to that fact and pay all filing and docketing fees; Ramirez’s failure to disclose his litigation history is ground for immediately terminating this appeal as a sanction for misconduct. See Hoskins v. Dart, 633 F.3d 541, 543 (7th Cir. 2011); Ammons v. Gerlinger, 547 F.3d 724, 725 (7th Cir. 2008).

Accordingly, the appeal is DISMISSED. Ramirez has 14 days from the date of this order to pay the appellate fees of $505. We also will enter an order directing the clerks of all courts in this circuit to return unfiled all papers he submits (other than collateral attacks on his imprisonment) until all outstanding fees are paid. See Ammons, 547 F.3d 724; Support Sys. Int’l, Inc. v. Mack, 45 F.3d 185 (7th Cir. 1995).
