Yeah for sure, all of em 

 Also shows it can be done.

If you encode the data in the pixels, give it a plausible title, YouTube will never even know it is being used as data storage, ESPECIALLY if it is encrypted. Even if they did know, what are the odds they scan every nostr note for a ref to that video and then parse whether the note is someone simply talking about the video (innocent) or posting a decrypting reference to the video. Then repeat that process for every video on their site they suspect might be storing data. I just feel like it would be so easy to fly under that radar for a very long time. I don't even know if its technically against their TOS. Because storing videos on YouTube is data storage. They just assume it is visual data. But who cares if it isn't? 🫡
