A VPN Hid My IP Address—But the Website Still Knew Me

The forum knew who I was before I typed a word.

I had turned on a VPN, selected a server outside the UK, and reopened a discussion about a private health issue. The age-check prompt that had stopped me earlier was gone. I assumed I was now browsing anonymously.

Then my usual profile picture appeared in the corner.

A half-written reply from the previous evening was still waiting in the text box. The site remembered my account, my preferences, and exactly where I had stopped reading.

I blamed the VPN. I disconnected, chose another server, and refreshed.

Nothing changed.

My public IP address was different, but the website still welcomed me by name.

I was trying to ask a question I did not want connected to my normal online identity. The subject was not illegal or dramatic. It was simply personal enough that I did not want it following me into advertising profiles, search suggestions, or the account I used for work.

Changing countries had removed the age-check interruption. It had not made me anonymous.

Why a new IP address feels like a new identity

This misunderstanding has become more common since the UK’s age-assurance requirements came into force in July 2025. Sites carrying certain adult or harmful content began introducing stronger checks, including facial-age estimation, identity documents, and credit-card verification. (Ofcom)

VPN use rose sharply afterward. A UK government consultation published in 2026 reported that daily usage increased from about 650,000 people before the requirements took effect to more than 1. (Eff) million at its August 2025 peak. (Gov)

The increase was not only about reaching content from another country. Public discussion also focused on surveillance, verification companies, and the discomfort of handing over a face scan or identity document to read something private. Research into the rollout found a sharp rise in both VPN searches and privacy-related discussion. (Arxiv)

That helps explain what many people expect a VPN to do. It changes the address a website sees, so it can feel as though the person behind the address has changed too.

But a VPN changes the route. It does not empty the browser’s memory.

My browser was carrying the stronger identifiers

The VPN had worked as a VPN.

My internet provider saw an encrypted connection to the VPN server rather than the forum itself. The forum saw the server’s IP address instead of the address assigned to my home.

It still recognised me because I had arrived with better identification than an IP address.

I was signed into my usual account. A cookie preserved the login. Other browser data remembered my settings and unfinished draft. Even after signing out, a site may recognise a returning browser through details such as its language, time zone, screen size, software version, and device configuration. (Eff)

The distinction was suddenly obvious:

A VPN changes where the traffic appears to come from.

It does not erase accounts, cookies, email addresses, phone numbers, payment details, or the identifying signals already stored in the browser.

A brief public VPN discussion made the same point through Gmail: changing the connection’s IP does not hide someone who then signs into an account bearing their name. (Reddit)

That was exactly what I had done. I had hidden the road to the forum while arriving with my name badge still attached.

Once I understood that, choosing a more distant server seemed irrelevant. The real task was to stop one sensitive session from reconnecting itself to the identity I used everywhere else.

The established provider added another permanent account

I had started with a major VPN company for sensible reasons.

It had years of public history, a large support operation, many independent reviews, and servers in almost every region I might need. Those are meaningful strengths for a service trusted with internet traffic.

The friction appeared before I connected.

I entered an email address, created a password, selected a subscription, and supplied payment information. That account became the place where my devices, plan, and VPN use were organised.

Once active, the tunnel hid my home IP correctly. But I had approached the service because I wanted fewer durable links around a sensitive browsing session. Creating another conventional account before I could begin moved in the opposite direction.

Then I reopened the forum in my normal browser and saw the same profile picture again.

The provider had changed my IP. It could not remove the identity already stored in the browser, and its own registration process had added another persistent identifier to the arrangement.

That failure changed the comparison.

Hundreds of server addresses would not help if my account, cookies, and trackers continued carrying the same identity between them. For this task, reducing persistent identifiers mattered more than producing a more distant IP address.

I needed to restart the identity, not just the connection

I closed the forum and opened a separate browser profile with none of my usual logins, cookies, saved passwords, or extensions.

Then I opened OnlydogVPN.

The smaller app did not require conventional email-and-password registration for basic use. Instead of creating another account trail before connecting, I could establish the protected route immediately.

Once it connected, I returned to the forum through the clean browser profile.

My usual avatar did not appear. The abandoned draft was gone. The site saw the VPN address rather than my home IP, while the browser arrived without the stored identifiers that had recognised me earlier.

I created a one-purpose alias and reopened the health discussion.

This time I could read it without being returned to my everyday account. I wrote the question, removed one detail that was more personal than useful, and pressed Post.

The message appeared under the alias.

That was the result I had actually wanted. I had not become an untraceable person. I had kept one sensitive question separate from the online identity attached to my work, ordinary browsing, and home connection.

The clean browser profile removed the old local identifiers. The VPN separated the session from my home IP and internet provider. The smaller app completed its part without requiring another conventional account before I could start.

The pieces worked because they solved different links in the same chain.

Fewer observers followed the new session

I returned to the thread later that evening. Two people had replied with the kind of calm, specific advice I had hoped to find.

While reading, I noticed the app’s blocked-request counter increasing.

The forum page was contacting services beyond the discussion itself. Some requests helped deliver the page. Others belonged to advertising or tracking systems designed to observe activity across websites.

This is where the idea of VPN anonymity often fails a second time. A tracker travelling inside an encrypted tunnel is still a tracker. Hiding the destination from the internet provider does not prevent the page from contacting outside companies after it loads.

The service’s tracker blocking reduced those extra connections before they left the device. The counter made the change visible without requiring me to inspect a technical log.

I could see which requests were stopped at the device level, but I could not inspect the service’s internal filtering rules or determine the purpose of every blocked request.

That limitation did not obscure the practical result. The original post was already separated from my normal account and home IP. Now fewer third-party requests were being allowed to follow the new session.

It was not the reason I had opened the app. It became the reason I kept it installed.

Anonymous is not a switch

The service has fewer locations, a shorter public history, and fewer independent ratings than the major provider I tried first. Those are real limitations for software trusted with network traffic.

But the larger provider’s server count had answered the wrong question.

I had assumed anonymity began when a website saw a new IP address. In reality, the forum had recognised my account and cookies without caring which country I selected. The useful change came only when I separated the browser identity, the network identity, and the VPN registration itself.

The established provider changed my IP after asking me to create another durable account. The smaller app changed the route without making email-and-password registration part of the process, then reduced the tracking requests surrounding the session.

A VPN did not make me anonymous. It removed one of the clearest links to me—and this one was more useful because it did not insist on replacing that link before I could ask a private question.
