Delete all Google Plus Posts, Comments, or +1's

Question

Is there a way to delete all of my posts, comments and +1's on my personal Google+ profile without deleting my Google+ account so I can keep my friends and acquaintances?

Answer 1

1. Go to https://plus.google.com/apps/activities/
2. Click on Posts, Comments, or the set of activities you want to remove.
3. Enter this code into the console:

document.body.style.height = "200%"; // Always allow to scroll to wake the ajax
(function deleteItems() {
    // All of the X buttons but from posts being removed
    const xButtons = document.querySelectorAll(".kKHdKc:not(.FmKyud) .XVzU0b.J3yWx");
    // If reached the end of the list
    const reachedEnd = window.getComputedStyle(document.querySelector(".Jb45He.SrWDEb")).getPropertyValue("display") !== "none";

    if (reachedEnd) {
        // Stop if no more buttons to delete
        console.log("No more buttons! Stopping");
        clearInterval(deleteInterval);
        return;
    } else if (xButtons.length === 0 && document.querySelectorAll(".kKHdKc.FmKyud").length === 0) { // No more buttons to press and it's not disposing of old comments
        // Scroll to wake up G+, an easier hack than calling G+ or loading all comments on a slow system
        window.scrollTo(0, document.body.scrollHeight);
        window.setTimeout(function() {
            window.scrollTo(0, 0);
        }, 10);
    }

    // Click the X buttons
    for (let i = 0; i < xButtons.length; i++) {
        xButtons[i].click();
        // Click the all the modals' delete buttons
        window.setTimeout(function() {
            let modalDeleteButtons = document.querySelectorAll(".HvOprf .RveJvd");
            for (let i = 0; i < modalDeleteButtons.length; i++) {
                modalDeleteButtons[i].click();
            }
        }, 3);
    }
    window.setTimeout(function() {deleteItems();}, 100); // Forces at least the syncronous tasks to finish which is why I used this over an interval
})();

4. Let it sit for a while.

If it stops after a while, change the three setTimeout delays to something larger. The 10, 3, and 5 ms times respectively were just some okay values for my system. I didn't put thought into them but rather just changed them when I noticed one part lag behind.

Be careful with code you enter into the console and don't enter code into the console unless you understand what the code does (as the self XSS warning in the console explains).

Answer 2

I wrote this javascript you can use in the console that will delete all posts and click the confirm box after clicking the x from the https://plus.google.com/apps/activities/ page.

var t = 500;
document.querySelectorAll('.XVzU0b.J3yWx').forEach(function(el,k) {
    setTimeout(function() {
        el.click();
        setTimeout(function() {
            document.querySelectorAll('.CwaK9 > span')[1].click();  
        }, 200);
    }, (t * k));
});

A slightly lower t (but greater than 200) should work too just a little faster.

The only official method without resorting to running scripts or hacks it to manually delete every post.
