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.
I firmly believe that quality content needs to be paid somehow. And I’d rather not have that ad based. But I’m open to other platforms too. I’m just giving this a go and there’s some good content on Nebula.
