SponsorBlock dev here

I never got any emails... I checked spam

But either way, this is just slop, KomoD's analysis is very good.

Everything mentioned here is intentional, SponsorBlock data is public, database dumps are published for anyone to download, and the API keys mentioned are not secret.

There are even third party sites that allow you to browse this data built on the database dumps: https://sb.ltn.fi/

Is it very trusting? Yes, but SponsorBlock is built on faith in humanity, and it's survived almost 7 years so far, with only a small amount of spammer firefighting.
