# Captcha (Private Messages)

The bot offers a command `/captcha` intended for use especially by servers that are infested with bots, such as Mirror Pass or Mirror Dao. This allows users to create a "private message" that is protected by captcha and therefore hidden from bots.

This can be used to post sensitive alphas that should be viewed by deserving users only, and not the general mirror public.

#### Parameters

* `message` - The message to display to users who successfully complete the CAPTCHA. This has a maximum length of 2000 characters.
* `button-text` - _Optional_ - Text of the button users click to initialize the CAPTCHA. Defaults to "View Message"
