Might get you part-way to deleting your Facebook wall?

bad-but-spunky-fb-wall-deleter.js

// In Chrome, go to your profile page. Open the Developer Tools Console
// (cmd + alt + j) and click the mobile phone button in the top left ("Toggle
// device toolbar"). I did this because it's easier to get around whatever
// guards are in place without worrying about hover states, etc.
//
// I chose "iPhone 5" in the device menu at the top of the browser window. That
// might be important, but probably not. I only ran this once ¯\_(ツ)_/¯
//
// Refresh the page, scroll down so you can see your posts, paste this into the
// console, hit enter, and enjoy the show for 20 seconds until it comes to a
// grinding halt.
//
// ^ Hopefully not. If it does stop, try manually deleting whatever caused the
//   issue, refreshing, crossing fingers, then going again. Repeat 4 delete.

// Here we go!
const steps = [
    // Click the chevron to open the menu.
    () => document.querySelector(
        '[data-sigil="story-popup-context-init"]'
    ).click(),

    // Remove the post, or hide it if it's someone else's content.
    () => {
        const remover = document.querySelector(
            '[data-sigil*="removeStoryButton"][data-sigil*="enabled_action"]');
        if (remover) {
            console.log('R E M O V I N G   P O S T !');
            return remover.click();
        }

        const buttons = Array.from(document.querySelectorAll(
            '[data-sigil*="afroDirectAction"][data-sigil*="enabled_action"]'));
        const hider = buttons.filter(button => button.querySelector(
            '[data-sigil="action-title"]'
        ).textContent === 'Hide from Timeline')[0];
        if (hider) {
            console.log('H I D I N G   P O S T !');
            hider.click();
        }

        // I think there's a third type of thing, where you want to click
        // "Untag something-or-other" rather than removing or hiding the post.
        // If that's the case, you might be able to do something like:
        //
        // const untagger = buttons.filter(button => button.querySelector(
        //     '[data-sigil="action-title"]'
        // ).textContent === 'WHATEVER THE BUTTON TEXT IS')[0];
        // if (untagger) {
        //     console.log('U N T A G G I N G   P O S T !');
        //     untagger.click();
        // }
    },

    // If you add something to the above step, you may need to go into your
    // Developer Tools inspector to see what the new confirm button's
    // `aria-label` is and add it to this list.
    () => document.querySelector(
        '[aria-label="Delete"], [aria-label="Hide"]'
    ).click(),
];

// That's it. It just runs through ^those three steps over and over again, with
// a ~1s delay between each step. You can probably decrease the delay time, I
// just figure it's rate-limited. Also, I wanted it to look really cool for my
// Instagram story.
(function nextClick (i) {
    console.log('R U N N I N G   S T E P   ' + i);
    steps[i]();
    console.log('R A N   S T E P   ' + i);

    setTimeout(() => nextClick((i + 1) % steps.length),
        700 + Math.random() * 500);  // <-- this is the delay.
})(0);

// Good luck deleting yourself!
