My guess is that would be very, very difficult without breaking a ton of other invariant assumptions throughout the system, like:
Video IDs are immutable
A video can only be represented by a single unique video ID
etc.
- bertil 3y agoYou could keep that assumption and just serve a random video if some external IP dials a non-existent ID. Presumably, no one would do that except researchers trying to count videos (or randomly find hidden ones?). You can break the assumption of unicity (if an unassigned ID is later assigned) if you do that internally, although not sure that’d be common but it’s not an assumption that has to be strict for non-attributed ones, and you never use the fake ID.
- tczMUFlmoNk 3y agoThis is easy to detect, though, at least for public videos. Click through to the channel on a different IP and find the video link, or search for the video's title and description, or find a canonical link to the video by any other means. If the IDs don't match, it's been faked.
- bertil 3y agoMaybe use a hash for consistency?
- j2kun 3y agoYou misunderstand that this technique was executed by using YouTube _search_ to find videos, not by querying the exact URL. They can doctor search results however they like.
