I'm talking about the unfair allegation of privacy violations, here. Note that when the Archive shares crawled content with other libraries, those other libraries often have their own legal right to collect, preserve, and make-available that data even stronger than the Archive's rights via fair use, implied-license, library privileges, and other grounds. For example, many of the Archive's partners in government libra…
Crawling and archiving everything, including personal writings, is a chilling effect. It is the same situation people are seeing with social media, where the past remains to haunt the present and none of our future leaders are using it without a mask. It was most surprising to people when some Libraries decided 'published' meant anything put on the WWW or posted to Usenet. It seemed grasp for funding and to keep rele…
On the larger issues, & specific to the Internet Archive:
You should assume there are several other larger "dark" web archives, by nations and large private organizations, collected without the awareness or available-remedies of the Internet Archive's or various national library public efforts. There are also uncountable other private and ad-hoc collections. Depending on what kinds of harms you expect from retained copies of older writings, these may be far larger threats than any holdings of an open, public, correctable non-profit library.
I would emphasize that anyone (like a web host or app) who gave any authors, especially the young & net-novices, the impression that something would stay private, or recallable, after being placed on a public webserver, at a published link, and open to browsing by all, did those authors a disservice by mis-informing them of risks, and the best-practices for preserving privacy.
That the Archive's well-identified, blockable crawlers sometimes surprise people with what they collect, and then make-available for lookup, helps correct that misunderstanding, both for individuals and the wider culture. Any "chilling effect" is unfortunate, but it's inherent to the web technology & practices of many independent actors. It's moreso documented, than created, by the Archive's own activities. And further – at least with respect to the Wayback Machine – the surprise availability is then fairly straightforward to undo, and prevent from recurring.
The broader risk that anything on the web – once offered to the public – will remain available from others persists no matter what the Archive does. Those concerned about such risks should take extra privacy-preserving steps, because blocking the Archive's crawls, or correcting the Wayback Machine, only limits this one polite, above-ground actor.
