W Social Bluesky concerns are growing as the European X alternative defends its reliance on US-built infrastructure. The platform presents itself as a European social network focused on trust, privacy, and sovereignty. However, it runs on the AT Protocol developed by Bluesky Social PBC, an American company.
That choice has sparked criticism. Some observers say the setup weakens W Social’s claim of being a sovereign European alternative. CEO Anna Zeiter rejects that view. She says the company needed a fast route to market and could not wait years to build every layer alone.
W Social Bluesky Infrastructure Helped the Platform Scale Faster
W Social uses the AT Protocol, the same technology behind Bluesky. This makes the platform interoperable with Bluesky, EuroSky, and other services using the same protocol.
As a result, users across those platforms can see each other’s public posts. Zeiter says this gave W Social access to an existing network of more than 43 million users.
Building proprietary software would have taken years. Instead, the company chose an existing protocol and focused on its own European infrastructure.
Zeiter says Europe needs a social media alternative now, not in three or five years. She describes the strategy as taking the best of both worlds.
W Social Says It Still Prioritizes European Infrastructure
Although W Social runs on the AT Protocol, the company says it controls key parts of its setup.
Its Personal Data Server is hosted by a European provider. The company also uses Proton, based in Switzerland, for email and calendar services.
Zeiter says W Social tries to stay as independent as possible. She also says the company mainly uses European infrastructure where it can.
The company is also building its own App View Server. That move should keep more data on European servers.
Verified Users Get a Separate Feed
W Social promotes itself as a platform with fewer bots. However, its link to Bluesky raised concerns because Bluesky does not require strict identity checks.
Zeiter says W Social solves this with separate feeds.
One feed only shows verified W Social users. Another feed includes posts from Bluesky, EuroSky, and other AT Protocol platforms. That wider feed can include users who have not verified their identity.
The company may add stronger protections later. Zeiter says that decision will depend on what users want.
There is still limited data on bot activity on Bluesky. However, one 2025 preprint study found that Bluesky’s moderation tools flagged or suspended many accounts that showed bot-like behavior.
European Hosting Claims Have Limits
W Social says it is hosted in Europe. Cybernews researchers say that claim needs context.
The platform can keep account data in Europe. This includes email addresses and user handles. However, public posts can still move across the wider AT Protocol network.
Cybernews analysis found that some services sit outside W Social’s full control. These include search, feed generation, content delivery, and network indexing.
Security researcher Aras Nazarovas says user-generated content can be synced and hosted outside the EU. This means W Social may not fully control all copies of public posts.
That could also affect deletion requests. Even if a user deletes an account, some public content may remain in the wider Bluesky infrastructure.
Zeiter says users need to understand this point. Anything posted publicly on W Social can be seen across the AT Protocol.
W Social Bluesky Links Create a Sovereignty Trade-Off
The W Social Bluesky connection gives the platform speed and reach. However, it also creates a sovereignty trade-off.
W Social gains access to a large decentralized network. It also avoids years of software development. Yet some data and services still rely on the wider AT Protocol ecosystem.
That makes the platform more open and scalable. At the same time, it makes full European control harder.
This tension sits at the center of the debate. W Social wants to offer a European alternative to X. But it also depends on technology created by a US company.
W Social Says Passport Data Is Not Stored
The biggest criticism of W Social has focused on identity verification.
Users can verify themselves through the W Identity app. The process can involve a passport or biometric data, such as a selfie.
Zeiter says W Social does not store passport information. She says the document is only used to check that the user is human and over 18.
After verification, the company says documents are deleted from its servers. Zeiter compares the process to showing ID at a nightclub or when buying alcohol.
She also says users can decide whether to join with their real name.
Experts Warn That Biometric Checks Still Carry Risk
Security experts remain cautious about the process.
Cybernews researcher Arnoldas Radišauskas says passport and biometric uploads create serious privacy risks. A password can be reset. A face or passport number cannot.
That concern remains even if W Social says it does not store the documents.
Zeiter says internal data is encrypted and hashed. In simple terms, the data becomes a unique digital footprint. She says it cannot be reversed with current technology.
Still, the debate shows a larger problem. Platforms want to block bots and fake accounts. But stronger identity checks can also increase privacy concerns.
Anonymous Users Can Still Join W Social
W Social does not force every user to verify with identity documents.
People can join anonymously with only an email address and user handle. Zeiter says this matters for users in dictatorships or unsafe environments.
However, anonymous users have limited powers.
They can read posts and like content. Their activity does not count in the algorithm. They also cannot take part fully in shaping public opinion on the platform.
Zeiter says this prevents a flood of bots while still allowing anonymous access.
W Social Defends Its For-Profit Model
W Social has also faced criticism for being a for-profit company.
EuroSky, another AT Protocol-based platform, runs as a non-profit through the Netherlands-based Modal Foundation. W Social chose a different path.
Zeiter says that choice was deliberate. She argues that a serious European rival to X needs private investment.
She says W Social is competing with a company owned by one of the world’s richest people. In her view, grants and donations alone would not be enough.
W Social Faces a Difficult Test
W Social is trying to solve several problems at once.
It wants to build a European alternative to X. It also wants to reduce bots, protect privacy, and scale quickly. To do that, it chose Bluesky’s AT Protocol instead of starting from zero.
That choice gives W Social speed and reach. However, it also creates doubts about sovereignty and data control.
The W Social Bluesky debate will likely continue as the platform grows. Its success may depend on how much infrastructure it can move into Europe while keeping the benefits of an open network.
