New comment by O4epegb in "Notion leaks email addresses of all editors of any public page"

I reported this and several other issues with public pages almost six years ago. Some of them were fixed after many years - but they're very slow to handle it. I never received any bug bounty or anything.

Here's a Reddit post just as confirmation: https://www.reddit.com/r/Notion/comments/hqyxid/possible_sec.... I also reported it privately two months prior, of course.

> The hooks system is the most underappreciated thing in what leaked.

Hooks is an official documented feature for quite a long time now https://code.claude.com/docs/en/hooks

> By the end of training, the model produces names like "kamon", "karai", "anna", and "anton". None of them are copies from the dataset.

All 4 are in the dataset, btw

This is a fake detector that just has frontend logic for mocking realistic data, you can easily see it in the source code.

You are confusing backwards and forwards compatibility. Those sites may have added features that your iPad does not support, which is why it broke, if they have not added those, it might still work.

However JS is not 100% backwards compatible either, it is in many cases, largely backwards compatible, but there are rare cases of bug fixes, or deprecated APIs that might be removed and break old code, but this is not even JS itself, it's more like web/engine standards.
