You could forge the list
You cannot forge a list of videos that are up on YouTube and ready to watch at any moment. Each video also has a date of upload that cannot be forged. By the way, if a user deletes his video, the website detects it and disables his account. That feature is built into the website.
The same goes for transactions on the blockchain. Past transactions cannot be forged.
I think it would make an interesting "use case" for @paragon and DashWatch to audit Dash.red. I welcome it. Perhaps it could help them to prepare for such things in the future.
