    27 |

    Turning this setting on lets ekill hold a grudge against any 28 | element you kill.

    29 |

    On subsequent visits to the same page, ekill will 30 | spot repeat offenders and carry out sweet vengeance.

    31 |

    FYI: This setting is strictly local. The 32 | Hit List is not shared across installations of ekill.
