CaptchaGuard is an easy-to-use bot for public chats. The bot sends a simple mathematical captcha to check if a new member of a chat is a bot. It is designed the way that a real person would complete it quite easily. Some examples of the captcha:
When a new member joins the chat, CapthaBot sends a query like this one:
If a new member happens to be a spam account, he won't respond correctly.
The user who failed to solve the captcha or ignored it counts as a bot and gets removed from the chat by CaptchaGuard.
The user who solved the captcha correctly, counts as a human.
This member is now verified and can start chatting!
They also get a greeting message if it was set by chat admin.
