YahooFinanceCommentBlocker is a Chrome extension that allows users to block others more freely on the Yahoo! Finance message board.

To block a user, simply use the "Register as an Extension Ignored User" button added to the comment menu. Unblocking is just as easy with the "Restore to Original" button in the same menu.

Additionally, users can save and load their list of ignored users in JSON format using the "Export Settings" and "Import Settings" buttons provided.

Please note that the developer does not assume any responsibility for damages caused by using this extension. It is developed in simple JavaScript without extensive features or support. The extension's ignored user list is separate from the official list and functions independently.
