Information that remains on archive sites and removal requests
Even if you delete a web page, that information does not necessarily disappear completely from the internet.
It can remain in search results, caches, republished copies, screenshots, and archive sites.
When thinking about anonymity, this is important.
Even if you remove your name or profile from the current page, old information can be traced if past pages were saved. Old handles, face photos, profiles, affiliations, activity histories, and past URLs become entrances that connect to current anonymous activity.
This article explains how to think about information that remains on archive sites, how to check it, how to proceed with removal or exclusion requests, and how to plan current anonymous activity when information cannot be removed.
What is an archive site?
An archive site is a service that saves past web pages so they can be viewed later.
A representative example is the operated by the Internet Archive. The Wayback Machine is a large archive for checking how past web pages were displayed.
The Wayback Machine is useful for research, journalism, document checking, and references to lost pages. On the other hand, for individuals, it can also be a place where old pages they thought they had deleted remain.
Archives are not bad things.
The problem is when old information affects current anonymity or safety.
What remains in archives
Effect on anonymity
Old profiles
Real name, region, affiliation, age range, and links connect to current activity
Past blog posts
Writing style, interests, usual places, and old handles remain
Company, school, or group pages
Affiliation and activity history remain
Images and PDFs
Face photos, creator information, and event information remain
Deleted pages
Information no longer visible now can be checked from past versions
Archives remain even if the original page is deleted
There is a point many people easily misunderstand.
Even if you delete the original page, saved pages on archive sites are not always deleted automatically.
For example, suppose you delete an old profile page. When you open the current URL, it returns a 404 error and seems to have disappeared from search as well. However, if that URL was archived before, the old display may remain.
For anonymity, this "past version" becomes a problem.
The current anonymous account resembles an old handle. The post content resembles an old blog. The region or job type left in the profile overlaps with current posts. In those cases, archives become material for correlation.
When checking archives, you need to look not only at current pages, but also at URLs you used in the past.
What to check
When checking archives, first list URLs related to you.
Searching only by real name or handle is not enough. Also check direct URLs you know, such as old blog URLs, profile pages, public social media pages, company or school introduction pages, event announcement pages, and PDF URLs.
Target to check
Reason to look
Old blog URLs
Check whether deleted posts or profiles remain
Old profile pages
See whether names, regions, links, or bios remain
Company, school, or group pages
See whether affiliation, role, or event participation information remains
Image file URLs
See whether images were saved directly even if removed from the page
PDF and document URLs
Check whether creator information, rosters, or handouts remain
Search results for old handles
Check whether they can lead to archived pages
One thing to watch is that archives are not limited to page-level captures.
Even if an HTML page is gone, image files or PDFs may have been saved directly. Even if blog body text is gone, titles or excerpts may remain on top pages or category pages.
Checking does not end once.
Review at different times, such as before starting anonymous activity, after changing a profile, and after sending a removal request.
How to think about removal and exclusion requests
If you want to remove information that remains in archives, first organize the original site side.
If the original page is still public, removing only the archive has limited meaning. First consider deleting the original site page, making it private, correcting personal information, replacing PDFs, and similar steps.
After that, check the archive site's removal request or exclusion request process.
Stage
What to do
Reason
1
Check whether the original page is still public
If the original information remains, it can be rediscovered
2
If you manage the page yourself, delete it or make it private
Address places where you have control first
3
If a separate administrator exists, request correction or deletion
Companies, schools, groups, and other people's sites require administrator action
4
Organize URLs that remain in archives
Clarify request targets
5
Apply according to the archive site's procedure
Methods differ by service
In a removal request, you may be asked for the target URL, the saved information, the reason it is a problem, and information showing that you are the person or administrator.
However, giving too much additional information for identity verification creates another risk. Check the necessary scope and carefully judge which contact point receives what.
If legal rights, defamation, harassment, information about minors, sexual images, or misuse of personal information are involved, also consider consulting a lawyer or support contact.
Difference from robots.txt and noindex
If you manage your own site, you may think about controls for search engines and crawlers.
Representative mechanisms include robots.txt and noindex.
However, these are not cure-alls.
robots.txt is an instruction that tells crawlers which areas they may crawl. noindex is an instruction to avoid listing a page in search results. Neither is a mechanism that necessarily deletes already saved archives or copies saved by third parties.
Mechanism
Main role
Caution
robots.txt
Tell crawlers which areas they may crawl
Not every party follows it, and it does not necessarily delete past saved copies
noindex
Avoid inclusion in search results
It is not a mechanism for deleting page contents
Original page deletion
Remove current public information
Archives and republished copies may remain
Archive removal request
Ask for deletion of saved pages
Depends on the service procedure and decision
These technical settings also enter the area of search-engine measures and site administration.
From the viewpoint of anonymity, it is important to understand that "not appearing in search" and "the information does not exist" are different.
When some archives cannot be removed
Archive removal does not always succeed.
The saved copy may be on another service, identity verification may be difficult, the information may be treated as having public interest, republished copies may exist in multiple places, or screenshots may have spread. In such cases, removing everything becomes difficult.
Even then, you can plan current anonymous activity in a way that does not connect it to that information.
Remaining information
What to avoid in current anonymous activity
Old handle
Do not use similar names, the same abbreviation, or the same profile text
Region or affiliation
Do not give detailed topics that suggest the same region or affiliation
Past writing style
Do not repeat the same endings, set phrases, or specialized phrasing
Face photos or event photos
Do not connect them to current images, activity, or friendships
Past URLs
Do not link to past URLs from new accounts
If there is information you cannot remove, include that information in the threat model.
In other words, assume "this information can be found if someone looks," and design current post content, images, timing, and accounts around that assumption.
Anonymity is not about completely erasing past information.
It is about not increasing material that connects past information to current behavior.
Summary
Archive sites can retain deleted pages, old profiles, images, PDFs, and event information.
Even if you delete the original page, archives, search results, republished copies, and screenshots are not automatically deleted.
First, check URLs related to you, old handles, past profiles, images, and PDFs. Next, consider original-page deletion or correction, requests to site administrators, and removal requests to archive sites in order.
Archives such as the Wayback Machine are socially important record mechanisms.
However, for individual anonymity, old information can also become an entrance that connects to current activity.
If there is information you cannot remove, redesign your operational practice around that assumption. It is important not to connect old handles, regions, affiliations, writing style, images, and past URLs to current anonymous activity.
