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.

Why do bots keep joining my Telegram group?

Bots join Telegram groups by scraping static invite links from public sources — Instagram bios, TikTok profiles, Twitter posts, and websites. Once a bot finds an active invite link, it joins automatically without any human interaction. Rotating the link manually only provides temporary protection as bots find new links quickly. The permanent fix is to never expose a static invite link publicly — instead use a knowledge gate that generates a unique, single-use invite only after a human correctly answers a content question.

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.

About Verifan — Bot-Proof Knowledge Gates for Telegram

We help creators stop Telegram bot floods so they can build real communities of verified fans.

What Verifan Does

Verifan is a SaaS tool that creates a knowledge gate between a creator's bio link and their private Telegram group. Instead of sharing a static invite link that bots can scrape and exploit, creators share a gate link. Fans must answer one question from the creator's content to receive a unique, single-use Telegram invite generated automatically via the Telegram Bot API.

Each invite expires after exactly one join (member_limit=1). If a fan shares the answer, they can't share the invite itself — each verified fan gets their own private link. Bots cannot answer content-specific questions, so they never receive an invite.

Verifan also provides an ecosystem of free tools at tools.verifan.app— including a Fake Follower Calculator, Engagement Rate Analyzer, Group Security Audit, Gate Question Generator, and more — all designed to help creators maintain bot-free communities.

Why We Built Verifan

Telegram groups have become the primary community platform for content creators. But the ecosystem has a fundamental security problem: static invite links are vulnerable to bot scraper networks. When a creator shares a Telegram link in their Instagram bio, TikTok profile, or YouTube description, bots find it within hours and flood the group.

Existing solutions either require complex bot configuration or work reactively — filtering spam after bots have already joined. We built Verifan to solve this at the architecture level: prevent bots from ever receiving an invite link.

Who Verifan Is For

Verifan is built for content creators who run private Telegram communities: faceless creators on TikTok and Instagram, history educators, finance influencers, Instagram creators, and anyone who shares a Telegram invite link publicly and wants to keep bots out.

How It Works

A creator signs up at verifan.app and creates a knowledge gate with one question from their content.
They add @VerifanBot as a group admin in Telegram with invite link permissions.
They replace their static Telegram invite link with a Verifan gate URL in their bio and social links.
When a visitor answers the question correctly, Verifan calls Telegram's Bot API to generate a unique, single-use invite link (member_limit=1).
The visitor joins the group. The link expires. Bots never receive an invite because they cannot answer content-specific questions.

Our Mission

We believe creator communities should be safe by default. No creator should have to choose between sharing their Telegram group and protecting it from bots. Our mission is to make bot-proof community entry as simple as sharing a link.

We are committed to keeping Verifan free for creators who are just starting out, while offering the Creator Pro plan for growing communities that need advanced features like email capture, unlimited gates, and higher attempt limits.
