This method allows Cyd to bypass X's API, ensuring continued access to user data even if API access is restricted.

• Data Backup: Before deleting any data, Cyd can create a local, searchable backup of a user's X data, including HTML snapshots of their tweets.

• Account Management: Cyd can help users who want to leave X while retaining their username. The app can delete all tweets and unfollow all accounts, leaving the account active but empty. This prevents others from taking over the username and allows users to leave a message directing followers to their new online presence.

• Likes and DM Deletion: Recognizing the potential privacy risks, Cyd can also delete a user's likes and direct messages.

RSS Parrot is a service that turns your Mastodon account into an RSS feed reader. To use it, you mention @birb@rss-parrot.net in a toot with the URL of the site you want to follow. This could be a blog with a dedicated RSS or Atom feed, a website, a Substack newsletter, a Bluesky profile, or a podcast.

Here’s how it works:

• RSS Parrot finds the RSS feed for the website. If it’s the first time someone has requested this site, it creates a new Mastodon account dedicated to it.

• This new account posts a toot every time there is a new post in the website’s feed. The account’s name is based on the website address, with dots separating each letter, and hosted on the rss-parrot.net server. For example, the account for taiwantrailsandtales.com would be @taiwantrailsandtales.com@rss-parrot.net.

• You then follow the RSS Parrot account to see the new posts in your timeline.

This allows you to stay updated on your favorite websites without leaving Mastodon.
