Twitter bulk tweet deleter. Run in twitter console. To get a `authenticity_token`, make a tweet on twitter.com, then check network. It's in the inspector. Doesn't appear rate limited (uses twitter's internal API), but hard to tell.

delete.js

// Download your archive and use the CSV to get IDs to delete.
var tweets = ["X", "Y", "Z"]

// See description about authenticity_token
(function() {

    var i = 0;

    var iterator = function iterator() {
        if ( i < tweets.length ) {
            var tweet = tweets[i]

            fetch('https://twitter.com/i/tweet/destroy', {
                method: 'POST', 
                credentials: 'same-origin',
                headers: { 
                    'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8',
                    'x-twitter-active-user': 'yes',
                    'x-requested-with': 'XMLHttpRequest',
                    'accept': 'application/json, text/javascript, */*; q=0.01'
                },
                body: $.param({ 
                    _method: 'DELETE',
                    authenticity_token: '%SEE ABOVE%',
                    id: tweet
                })
            }).then(() => {
                i++; iterator();
                
            }).catch(( error ) => {
                console.log( error );
                i++; iterator();
            });
        } else {
            console.log('Done!');
        }
    }

    iterator();

})();

In order to get the IDs I wanted to delete, I made a small script locally that used React to narrow down tweets. Using a blacklist to blanket remove some terms, and a rule to delete all but 5 tweets for every month of twitter history before one year ago. I recommend making a cool UI yourself to narrow down tweet IDs from archive.

Enjoy.
