How do I stop bots from joining my Telegram group?

The most effective way to stop bots from joining your Telegram group is to use a knowledge gate instead of sharing a static invite link. A knowledge gate requires anyone who wants to join to answer a question from your content first. Bots cannot watch your videos or read your posts, so they cannot answer correctly. Verifan automates this — creators set one question, and every correct answer generates a unique, single-use Telegram invite link automatically via the Telegram Bot API.

What is a single-use Telegram invite link?

A single-use Telegram invite link is a link that can only be used to join a Telegram group once. After one person clicks it and joins, the link expires permanently. This prevents link sharing — even if someone forwards the invite to a friend, the link is already dead. Verifan generates a new single-use invite link for every fan who passes the knowledge gate, using the Telegram Bot API createChatInviteLink method with member_limit set to 1.

What is a knowledge gate for Telegram?

A knowledge gate is a checkpoint between your bio link and your private Telegram group. Instead of sharing the group invite link directly, you share a gate link. Anyone who clicks it must answer a question correctly before receiving an invite. For content creators, the question is something from their actual content — a detail from a video, post, or story. Real fans know the answer. Bots do not. Verifan provides knowledge gates with automatic single-use invite generation.

Is Verifan free to use?

Yes. Verifan has a free tier that includes one knowledge gate, 50 fan attempts per month, and single-use Telegram invite generation. No credit card is required. The free tier includes a Powered by Verifan watermark on the gate page. Creator Pro at $12 per month removes the watermark, allows unlimited gates, 10000 attempts per month, and fan email capture.

How to Filter Bots From Your Telegram Group — Bot-Proof Telegram Gates

Verifan uses content-knowledge gates to verify humans. If they don't know the answer to your question, they don't get the link. Simple, effective, and impossible for bots to bypass. Fake members and Telegram group bots are blocked at the entry point — no invite link is ever generated for them. Follow the step-by-step guide to set up your bot filter in minutes.

Content-Knowledge Verification

Unlike CAPTCHAs which bots are getting better at solving, Verifan relies on what your fans know. By asking a question about your recent video, post, or podcast, you ensure only active community members can join.

Customizable questions
Fuzzy matching for answers
Zero friction for real fans
Total protection from automated spam

Setup: Add Telegram Bot to Group Gate

To set up Verifan as your bot filter, add @VerifanBot to your Telegram group as an admin. The bot needs invite link permissions to generate single-use invites for verified fans. Once added, create a gate with one question from your content and share your gate URL. That's it — bots are blocked before they ever see an invite link.

Frequently Asked Questions

Why do bots keep joining my Telegram group?

Bots use automated scripts to scan social media bios, websites, and search engines for Telegram invite links. Any publicly exposed static link is vulnerable. Once found, bots share the link across networks and join your group in large numbers. This is especially common for faceless creators and history creators who share invite links in their bio.

How do I stop bots from flooding my Telegram group?

The most effective way is to never expose a static invite link publicly. Use a knowledge gate that requires visitors to answer a content question before receiving a unique, single-use invite. Bots cannot answer content questions, so they never receive an invite link.

What is the difference between a Telegram bot filter and a knowledge gate?

A Telegram bot filter is reactive — it detects and removes bots after they have already joined your group. A knowledge gate is preventive — it stops bots from ever receiving an invite link. Knowledge gates are more effective because bots never get inside to cause damage.
