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 Waow. Funny. I was expecting Youtube for more than 10 years to start doing that, as it would be the only way to insert almost unblockable ads in video streams.

But as long as ads are clickable it's ok as you said.

But in the end they might add unclickable ads... maybe in 10 years :D
