Techies keep forgetting that you can’t just do whatever you want with other people’s data.
@baldur I see the opt-out this tool wants is via HTTP headers. That’s harder to support than robots.txt. Perhaps more tellingly, immediately after describing the opt-out headers, the readme describes how to circumvent even that.
To disable this behavior and download all images, you may pass --disallowedheaderdirectives '[]'
Appalling.
