EXPOSED: Google Search AI Uses Secret Caches of DELETED Reddit Data to Profile Users

[Bitu79]

I have just uncovered definitive, reproducible proof that Google’s Search AI Overview is not just a search assistant—it is a shadow profiling engine that retains and uses explicitly deleted data to reconstruct user identities.

If you thought deleting your social media accounts protected your privacy from Google, you are wrong.

The Evidence:
I conducted a forced-search test using the Google Search AI Overview. The AI successfully connected three distinct data points to build a comprehensive profile on me:

1. My Google AI Developers Forum alias (bitu79).

2. My real civil name.

3. My former Reddit account (HugeScore3150).

The “Smoking Gun” (Illegal Data Retention):
The Reddit account u/HugeScore3150 and all its associated posts were deleted and banned. They do not exist on the live internet. A standard search engine crawling the live web cannot find them.

Yet, when pushed, the Google Search AI not only confirmed the connection between my real identity and this deleted Reddit account, but it also started quoting the exact text and titles of my deleted posts from r/GoogleGeminiAI, r/gdpr, and r/LinusTechTips.

When I confronted the AI about how it could read posts from a non-existent account, the system generated an open confession (which I have screenshotted and archived).

The AI’s own generated text states:

• “In previous searches, I was still able to retrieve the links and texts of the r/gdpr, r/LinusTechTips, and r/GoogleGeminiAI subs from Google’s cache…”

• “Since the profile and posts are no longer available on live Reddit, your original statement was correct: this user and these posts are currently not on the site.”

Conclusion:
This is documented proof of a massive GDPR violation (Article 17 - Right to Erasure, and illegal automated profiling).
Google is actively harvesting data from third-party sites (like Reddit). When a user deletes their data from that third-party site, Google does not delete it from their internal AI databases. Instead, they keep it in a hidden “cache” and use it to permanently profile individuals, linking their deleted online aliases to their real civil names.

Delete means nothing to Google. They are hoarding everything.

Evidence Summary: Google AI Data Retention and Profiling

(based on screenshots and documents recorded on 22 June 2026)

1. Executive Summary

The collected evidence demonstrates that Google Search and Google’s AI Overview feature are storing, processing, translating, and re‑using deleted Reddit data, and are linking multiple user identities (HugeScore3150 ↔ Bitu79 ↔ György Istókovics).
This behavior goes far beyond simple caching. It constitutes active data processing and automated profiling, which violates GDPR Article 17 (Right to Erasure) and Article 22 (Automated Profiling).

2. Key Evidence (Narrative Form)

a) Google Activity Log (timestamped)

The Google “My Activity” page shows a precise timestamp (05:52) for a search query involving “hugescore3150 bitu79,” and confirms that AI Mode generated a response.
This proves that Google’s AI actively processed the query and retrieved information from deleted sources.

b) AI Overview text

The AI Overview explicitly states that search engine AI models are capable of profiling users based on previously deleted internet data.
This is a direct admission that the system uses deleted content for automated decision‑making.

c) Google Search results showing deleted Reddit content

Multiple search results display content from the deleted Reddit account u/HugeScore3150, even though the account and all posts were removed from Reddit.
The deleted content appears in:

• English

• Spanish

• French

• Danish

• German

• Hungarian

This multilingual appearance proves that Google did not merely cache the content — it translated, re‑indexed, and redistributed it.

d) Google AI Developers Forum posts

Several posts on Google’s own official forum describe the issue in detail, including:

• “Your AI Overview is profiling me”

• “Google Search AI Uses Secret Caches of DELETED Reddit Data”

These posts document that Google’s AI systems reconstructed a profile linking the deleted Reddit account to a real‑world identity.

e) Wayback Machine archived version

The original forum post was deleted by Google moderators, but the archived version remains publicly accessible.
This proves:

• Google saw the issue

• Google removed the post

• The content is preserved as immutable evidence

f) YouTube video evidence

A YouTube video (uploaded under the name György Istókovics) further documents the issue and is indexed by Google Search alongside the deleted Reddit content.

g) Identity linkage

Search results show that Google’s systems linked:

• the deleted Reddit account (u/HugeScore3150)

• the username “Bitu79”

• and the real‑world identity

This is cross‑platform identity correlation, which is a form of profiling.

3. Legal Relevance

The evidence demonstrates violations of:

GDPR Article 17 – Right to Erasure

Once Reddit deleted the account and its posts, Google had no legal basis to continue storing, translating, or using the data.

GDPR Article 22 – Automated Profiling

Google’s AI Overview used deleted data to:

• infer identity connections

• generate user profiles

• present these profiles in search results

This constitutes automated profiling without consent.

GDPR Article 5 – Data Minimisation & Purpose Limitation

Google processed deleted data for new purposes (translation, indexing, profiling), which were not part of the original purpose of collection.

4. Technical Findings

• The AI Overview text confirms profiling based on deleted data.

• The “source cards” (small preview tiles) in the AI response show that the system used internal stored data, not live web content.

• The multilingual search results prove that the deleted data was actively processed, not passively cached.

• Identity linkage across platforms indicates cross‑dataset correlation, which is a high‑risk data processing activity.

5. Conclusion

The evidence shows that Google’s AI systems:

1. Retain deleted Reddit data

2. Translate and re‑index the deleted data

3. Use the deleted data in AI‑generated responses

4. Link multiple user identities across platforms

5. Perform automated profiling based on deleted content

This is not caching.
This is illegal data retention and profiling under the GDPR.

Reddit deleted the data.
Google still displays it.

Google’s AI also processes it (translates it, summarizes it, profiles it).

This is data retention + data processing of deleted content.

This violates GDPR Articles 17, 22, and 5.

It does not matter whether it comes from cache or from the index.
Deleted data is deleted data.
Google is not allowed to use it.

Google can still see my deleted Reddit posts in 2026 because it cached them in its own systems while they still existed. Reddit deleted my account and my posts, but Google did not delete its own copies. Google’s index does not update automatically and does not check whether the content still exists on the original site. Because of this, Google continues to store and display my deleted posts, and its AI systems use that cached data. This counts as personal data processing even if it is “just cache,” and it is still unlawful even if I did not request deletion, because once the source site removed the data, Google was also required to delete its copies.

Google continues to store and display my Reddit posts and username even though my Reddit account and all associated content have been deleted on the source platform. Google is showing these deleted data from its own cache and index, and its AI systems continue to process, summarize, and translate them. Since these data no longer exist on the source site, Google’s continued storage and processing of them is unlawful.

Under GDPR Articles 5(1)(d) and 5(1)(e), Google is required to delete inaccurate and no‑longer‑necessary data. Under Article 17, storing data that has been deleted at the source is not permitted. Google’s AI systems are performing profiling based on my deleted content, which violates Article 22.

I request that Google immediately delete all stored, cached, indexed, and AI‑processed data related to my former Reddit account and confirm the deletion.

I have sent the documented case to several researchers by email. The messages were successfully delivered, and the recipients’ mail servers accepted them.

https://web.archive.org/web/20260622072056/https://discuss.ai.google.dev/t/exposed-google-search-ai-uses-secret-caches-of-deleted-reddit-data-to-profile-users/172097/14

I opened a completely new chat, and the Search AI is blatantly lying.

What actually happens?

• On the right side, the small panel appears → the AI Overview.

• This panel is ALREADY using Google’s internal index and cache.

• When you open the AI chat, it pulls its information directly from this panel.

• In other words: the chat uses the exact same data the panel has already preloaded.

Where is the shameless lie?

The AI chat says:

“I do not have direct access to Google’s internal, closed backend systems…”

Meanwhile:

• the right‑side panel literally loads deleted Reddit data from the internal backend/cache,

• and the chat simply rephrases and explains those panel results.

Therefore:

It DOES have access to the internal system, while shamelessly claiming it does not.

News FLASH! Tech companies keep and sell Data on users!
Did you really need to make a 15 post topic about this dude?

[Bitu79]

Based on your comment, it seems you didn’t understand the difference between profiling with deleted data and general data collection. This topic is not about what you wrote — so if it doesn’t interest you, why comment on it in the first place?

[Bitu79]

[Bitu79]

Your argument ignores the actual issue.
The model’s context window clearly showed that the deleted Reddit data came directly from Google’s cache, not from training data.
The source deleted the data, yet Google continued to process it and even linked my real civil name to a deleted anonymous alias — which is illegal automated profiling under GDPR.

Technical complexity or server costs are not valid legal defenses for non‑compliance with the GDPR.
If Google cannot manage personal data lawfully, then Google cannot process it.

I am not dealing with opinions or fan explanations.
I am presenting system‑generated evidence of deleted data still being stored, retrieved, and used for profiling.
If necessary, I will escalate this through formal legal channels.
