YouTube is currently experimenting with server-side ad injection. This means that the ad is being added directly into the video stream.

This breaks sponsorblock since now all timestamps are offset by the ad times.

For now, I set up the server to detect when someone is submitting from a browser with this happening and rejecting the submission to prevent the database from getting filled with incorrect submissions.

@sponsorblock They are spending a lot of time and money to ensure that people see ads. Be great if they invested that much energy into improving the user experience
@TrackerRoo how does that benefit the shareholders?
@sponsorblock @TrackerRoo This made me laugh and also cry a little inside

And @sponsorblock is investing a lot of time and money into playing along with Google's game.

Imagine if all that were spent on improving the user experience on open platforms, so we could stop playing Google's game!

(Yet, thanks for the effort! It sure improves life for YouTube consumers, I just don't consider it sustainable.)
