/start

Hello, I am a Bot that send an image captcha for each new user who joins a group, and kick anyone that can't solve the captcha within a specified time.

If a user tries to join the group 5 times in a row and never solves the captcha, I will assume that this "user" is a bot, and it will be banned. Also, any message that contains a URL sent by a new "user" before the captcha is completed, will be considered spam and will be deleted.

Remember to give me administration privileges to kick-ban users and remove messages.

Check /help command for more information about my usage.
