Fight spam on your Telegram group with hCaptcha

Introduction

Telegram has become an increasingly popular chat option in recent years, now boasting hundreds of millions of monthly users. However, popular Telegram groups are bombarded by spam due to a lack of built-in protections on the platform.

In our attempt to make the internet a safer and more pleasant place, we are introducing a public Telegram bot for Telegram group admins to keep spammers from joining and participating in your conversations.

It is an easy-to-use addition to a group that requires new users who wish to comment in your group to first pass a hCaptcha challenge.

How to start using it

1. Invite the bot to your group and give it admin permissions.

2. Ask the bot to restrict the group. It does not start restricting users until you enable it.

3. New users joining will be asked to solve a hCaptcha before they are allowed to chat.
