No.

This isn’t a passive “walked by the window” thing that you might have unwittingly viewed. To actively search for open cameras by crawling every IP then creating a tool to see them, then choosing to watch the footage is a very active, deliberate choice. No one is viewing this footage without making a multi-step choice to view it.

Don't confuse the creators and maintainers with people who click on a link out of curiosity. I also briefly "walked by the window" glancing at cats using automated feeders in china when someone posted that page to HN recently.

I'm surprised this is still a thing though. I remember being shocked when I came across an extensive feed of these inadvertently pubic CCTV feeds ~15 years ago. I had assumed it was no longer a problem.
