自动回复隐藏帖 is a free Chrome extension developed by micalee. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This extension supports all forums that utilize Discuz! software. Its main function is to automatically reply to hidden threads by selecting a random pre-defined message. If the user is not logged in, the extension will prompt and guide them to log in.

Upon installation, 自动回复隐藏帖 comes with two pre-set reply messages that can be edited or deleted as per the user's preference. If all pre-defined messages are removed, the extension will display a comment box every time a hidden thread is detected.
