Bot help:
————————————————
- I am a Bot that sends a captcha for each new user that joins a group, and kick any of them 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 the "user" is a bot, and it will be banned.
- Any message that contains an URL that has been sent by a new "user" before captcha is completed will be considered spam and will be deleted.
- You need to grant me Administration rights so I can kick users and remove messages.
- To preserve a clean group, I auto-remove all messages related to me when a captcha is not solved and the user was kicked (after 5 minutes).
- The time that new users have to solve the captcha is 5 minutes by default, but it can be configured using the command /time.
- You can turn captcha protection on/off using the commands /enable and /disable.
- Configuration commands can only be used by group Administrators.
- You can change the language that I speak, using the command /language.
- You can configure captcha difficulty level using command /difficulty.
- You can set captcha to use full numbers and letters A–Z, or numbers and letters A–F, or just numbers (default), or just a button, using command /captcha_mode.
- You can configure a custom welcome message with command /welcome_msg.
- You can enable an option to let me apply restriction to new joined users to send non-text messages using command /restrict_non_text.
- If the Bot is Private, allow groups with command /allowgroup.
- Check /commands to get a list of all avaliable commands, and a short description of all of them.
