Per Curiam.
This Court issued an order on May 9, 2018, directing Appellant to show cause why sanctions should not be imposed against him in light of his having instituted repetitive, meritless proceedings in this Court. See State v. Spencer , 751 So.2d 47 (Fla. 1999).
We have reviewed Appellants response and determined that it does not provide a legal basis to justify withholding imposition of sanctions.
Appellant is hereby prohibited from filing any pro se filings in this Court challenging his conviction and sentence in Dade County case number 98-35550. The clerk of this Court is directed not to accept any filing in this case unless it is signed by a member in good standing with the Florida Bar. Appellant is warned that any filings that violate the terms of this opinion may result in a referral to the appropriate correctional institution for disciplinary proceedings.
AFFIRMED .
Roberts, Rowe, and Winokur, JJ., concur.
