                Delete your old tweets with this disgusting bash script
              
          
    100% free. Runs completely locally on your machine. Bypasses the 3200 tweet limit.
May require some eye bleach for the script. Here's how to use it:


Go to settings -> account -> your Twitter data and request a download.
This may take a few hours. You'll get an email with a link to download a zip file.
Extract the zip file and navigate to the data directory.


Go to Twitter in a web browser and find any Tweet you want to delete.
We're going to use it to extract your authentication credentials for the
next step. Open developer tools, delete the tweet, and find the request

duplicity -> Backblaze B2

Daily systemd timer to backup the contents of my filesystem to Backblaze B2. As-written, it will keep up to
a year's worth of backups, performing one full backup every month. This script was tested with duplicity 3.0.3.
