FLVoters is a data broker website that posts information from Florida Voting Records. Removing yourself from FLVoters requires you to write them a letter requesting access. As a result, it may take 7 or more days for your information to be removed.
Option One: Go to the individual detail page (the desktop version, not the mobile-friendly version) showing your name. Scroll down and submit a removal request online. Option Two: Download the .rtf or .txt file, get it notarized so they can confirm your identity:
PO Box 106
Option Three: You may instead mail in a photocopy of the voter information card the elections people provided to you when you registered.
