Poisoning AI with ".аss" subtitles

Summary

Key Points

• Many low‑quality YouTube videos are generated by AI using scraped subtitles and text‑to‑speech, resulting in robotic narration and repetitive stock footage. 0:26
• This practice, called “Faceless YouTube Channels,” exploits AI tools to produce content without human effort, stealing ideas from existing videos. 1:46
• The technique also works around caching mechanisms by uploading a dummy “yapping” version of the video to fill summariser caches, then swapping back to the original content. 6:36
• When AI summarisers scrape these subtitles, they generate nonsensical summaries because they read the concealed garbage instead of the real dialogue. 9:01
• The creator demonstrates a method to poison AI summarisers by adding invisible, out‑of‑bounds subtitle text using the ASS subtitle format. 9:24
• The creator provides a Python script that automates inserting invisible subtitle chunks and adjusting styles, making the protection scalable. 9:50
• By converting ASS subtitles to YouTube’s YTT format, the hidden garbage text remains in the file while viewers see only the correct captions. 10:12
• Limitations include mobile players that don’t respect transparency or positioning and summarisers that use audio‑based transcription like Whisper. 12:45
• While not a permanent fix, the method raises the cost for AI thieves and encourages developers to improve anti‑plagiarism safeguards. 16:58
