Add captcha option to Share function in Confluence

Problem

When using the Share function on a Confluence page, it allows users to send e-mails from Confluence to other users, which has the potential to create spam, as there is no limitation on using the Share functionality.

Suggested Solution

Adding the possibility of configuring Confluence's already existing captcha functionality, to affect the Share option as well, could solve this issue.

Why This Is Important

This would prevent the possibility of spam being created by using the Share option, which would otherwise disrupt users, and makes the application more reliable.

Workaround

There are no workarounds available at this time.
