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 see YouTube style as the ones that are formulic with the plea to like and subscribe segue to sponsor and the obviously algorithm driven increased lengthen followed by the same tired robotic plea for interaction which is pretty much every big YouTube channel or wannabe big channel.
Doesn’t help that search pushes up those type of channels and shoves smaller channels just uploading content just to share something.
