Telegram Watchdog

Telegram Watchdog is a verification bot for Telegram groups focused on blocking spam bots and automated accounts. It adds a simple CAPTCHA step for every new member and only lets users who pass the test stay in the chat.

Core functionality

Once added as an admin, the bot monitors new joins and sends each newcomer a verification challenge. Users who fail or ignore the CAPTCHA within the configured time window can be restricted or removed, depending on the group settings.

Use cases

The bot is suitable for public communities, private groups, and discussion chats attached to channels. It reduces manual moderation work, protects from mass bot attacks, and helps keep conversations on topic.

Key features

• automatic verification of new members;
• CAPTCHA to distinguish humans from bots;
• protection against spam floods and fake joins;
• operation across multiple groups with configurable behavior.

Telegram Watchdog focuses on straightforward, reliable onboarding control rather than complex moderation logic.
