A tool for protecting Telegram group chats from bots, spam, and automated attacks. When a new member joins, the bot sends an image-based captcha and provides a limited time to solve it. Users who fail the verification are automatically removed from the chat. After repeated failed attempts, the system identifies the user as a bot and blocks them. Until verification is completed, all messages containing links are treated as spam and removed. The bot supports flexible configuration: captcha types, difficulty level, response time, language, welcome messages, and penalties. The solution helps keep chats clean and reduces the workload for administrators.
