The IETF has termed pervasive monitoring as an “attack[4], recommending all traffic be sent over HTTPS to avoid said attack. Similarly, the United States CIO has stated that “All browsing activity should be considered private and sensitive. An HTTPS-Only standard will eliminate inconsistent, subjective determinations across agencies regarding which content or browsing activity is sensitive in nature”. [5]

Regardless, there there be an opt out mechanism, similar to a robots.txt on a standard web page? I especially worry about the issue of harassment, which has been raised with other annotation services like Genius[7].

I encourage other standards developers to consider using the self questionnaire - and I welcome feedback on how this questionnaire can better help spec authors perform privacy audits:

> >>      • Does the data record contain elements that would enable re-correlation when combined with other datasets through the property of intersection (commonly known as "fingerprinting")?
> >>              • However I would like to point out that PING  has previously discussed sensor-specific question that can get at cross-device or cross-UA signaling. (The Vibration API). Can I get a volunteer to submit a pull request to add language that would add language to capture this threat model to the existing questionnaire?

> >>              • Again, not clear if users will have the ability to delete/edit annotations. Hopefully there will be a discussion on this feature - users often regret posts on social media[8], and it’s important they be able to delete their posts.
