YouTube Anti-RickRoll Userscript

Features

• The script checks YouTube video titles, songs, keywords for common RickRoll indicators.
• It fetches a list of known RickRoll videos from an external database.
• If a suspected RickRoll is detected, it prevents the video from playing and alerts the user.

How It Works

• RickRoll Detection: The script examines the video title, songs, and keywords for common phrases such as "RickRoll" or "Rick Astley".
• External Database: The script fetches a list of known RickRoll videos from a publicly accessible GitHub repository and checks if the current video is on that list.
• Warning: If the video matches the criteria, the script prevents the video from playing and shows an alert warning the user that it is likely a RickRoll.
