A quick way to delete all your tweets using Twitter archive and a ruby script.

How to delete all tweets with Ruby fast

require 'twitter'
require "json"

USERNAME = 'YOUR_TWITTER_USER_NAME'
ARCHIVE_PATH = 'archive/data/js/tweets'

client = Twitter::REST::Client.new do |config|
  config.consumer_key = 'TWITTER_APP_API_KEY'
  config.consumer_secret = 'TWITTER_APP_API_SECRET'
  config.access_token = 'TWITTER_APP_ACCESS_TOKEN'
  config.access_token_secret = 'TWITTER_APP_ACCESS_TOKEN_SECRET'
end

Dir.foreach(ARCHIVE_PATH) do |item|

  unless (item == '.') or (item == '..') or (item == '.DS_Store') 
    #ignore system files and paths
    
    file = File.readlines("#{ARCHIVE_PATH}/#{item}")[1..-1].join()
    data = JSON.parse(file)

    data.each do |tweet|
      removeId = tweet['id']
      begin
        client.destroy_status(removeId)
        puts "destroyed tweet_id: #{removeId}"
      rescue => e
        puts "ooops: #{e} -- t_id: #{removeId}"
      end
    end
    
    sleep(60)

  end

end

@Rishi333 good point. I will rework it to be more obvious.
