Can a public proxy operator read my messages?

No. MTProxy operates at the transport layer — it does not have access to message content. Telegram encrypts data before transmission. However, the operator sees the connection event, your IP address, and activity timings.

How serious is the risk of subscribing to spam channels through a proxy?

The proxy operator can change the TAG (Promoted Channel) in the config at any time. Technically, nothing prevents them from rotating spam channels. Telegram has no mechanism to limit the frequency of changing the promoted channel.

MTProxyHub aggregates proxies from verified sources and updates the list every 60 seconds, removing dead ones. We do not control specific servers, but we filter out obviously malicious ones.

Should I trust proxies from Telegram channels?

With caution. Channels with a large audience and a long history of publications are more reliable. Anonymous channels created recently carry a higher risk.

Public MTProxy Risks: What Free Proxies Hide

Q: How can I find out who owns a proxy?

In the tg://proxy link, you can see the server's IP address. The command whois will show the provider and the country of registration. This does not reveal the owner's identity but provides basic information.

There are thousands of free MTProxy servers on the internet. They are easy to find in Telegram channels, on websites, and in social networks. The appeal is obvious: no need to pay or install anything — just click a link and connect. But "free" never means "without a cost".

What Happens When You Connect to a Public Proxy

When you connect to an MTProxy server, all your Telegram traffic goes through that server. The server operator sees:

It is important to understand: the operator cannot read the contents of your messages — MTProto encrypts data at the application layer. But the connection metadata is exposed.

Risk 1: Promoted Channels and Spam

This is the most common and legally permissible "risk". Every MTProxy has an optional TAG parameter — a Promoted Channel identifier. The channel with this tag is automatically pinned to the top of the chat list for all connected users.

Technically, this is Telegram's official monetization mechanism. Problems arise when:

The channel is spam or crypto schemes
The operator regularly changes the channel (you never know what will be pinned tomorrow)
Multiple channels are promoted simultaneously through rotation

Telegram does not limit the frequency of changing the TAG in the config. An operator can change the promoted channel even every hour.

Risk 2: Metadata Interception

MTProxy cannot read your messages, but it collects connection metadata:

What the operator sees	What it means
Your IP address	Your physical location (down to city/provider)
Connection time	When you are online in Telegram
Session duration	How long and how often you use Telegram
Traffic volume	Roughly how many messages/media you receive

For most users, this is unpleasant but not critical. However, if you are in a country with an authoritarian regime and the authorities get access to proxy logs — your Telegram activity will be documented.

Risk 3: Instability and Overcrowding

Free public proxies are often set up on the cheapest VPS. When such a proxy is published in a large Telegram channel, thousands of users connect to it.

Consequences:

Slow media loading and message delays
Regular connection drops
Complete unavailability during peak hours

Providers allocate a specific bandwidth to each VPS. When 10,000 users share a 1 Gbps channel, everyone gets ~100 Kbps.

Risk 4: Legal and Jurisdictional Risks

A less obvious but important risk. Some public MTProxy servers are located in countries with aggressive internet surveillance laws. The operator may be required to provide data to local authorities upon request.

This does not mean the content of your messages will be known — MTProxy does not see it. But your metadata (IP, activity time) might be handed over.

Another point: in some countries, simply using a proxy to bypass blocks is technically illegal. Connecting through someone else's proxy doesn't create additional risks compared to a VPN, but it is worth considering.

Risk 5: Intentionally Malicious Proxies

An extreme scenario, but it exists. Although MTProxy cannot decrypt the content of MTProto messages, connection-level attacks are theoretically possible:

SSL stripping for unprotected connections (not MTProto, but other connections going through the same network)
Traffic analysis to profile user activity
Injections into unencrypted traffic (if you visit an HTTP page, though this is not Telegram-specific)

These attacks are not trivial and require specific conditions, but they are possible in the context of targeted surveillance.

How to Mitigate Risks When Using Public Proxies

If you still need a public proxy, here is how to minimize the risks:

Use verified aggregators, not random links. MTProxyHub checks node availability every 60 seconds.
Prefer proxies with Fake TLS (secret starting with ee). This is not protection against the operator's actions, but a sign of a more competent setup.
Check the server's geography — whois IP will show the country and provider. Avoid servers in countries with strict internet laws.
Do not use a single proxy permanently. Rotation reduces the amount of metadata available to one operator.
Use Secret Chats for important conversations — they use E2E encryption with keys only on your devices. The proxy does not affect their security.

When It Makes Sense to Set Up Your Own Proxy

Your own MTProxy takes 30 minutes and $3–5/month:

	Public Proxy	Your Own Proxy
Cost	Free	~$3–5/month
Promoted Channel	Someone else's, changes	None, or your own
Metadata	With the operator	Only with you
Stability	Low when overloaded	High
Setup	30 seconds	30 minutes

FAQ

Can the operator read my messages? No. MTProxy has no access to the content — Telegram encrypts the data before transmission. But the operator sees the metadata: your IP and activity timings.

How serious is the risk of spam channels? The operator can change the Promoted Channel at any time. There are no technical limitations — only reputational ones.

Is MTProxyHub safe? We aggregate proxies from verified sources and update the list every 60 seconds. But we do not control specific servers.

How can I find out who owns a proxy? whois <IP> will show the provider and country. You cannot find the owner's identity without their consent.
