We have a Confluence site and noticed the following. When a user uses their email address as their username, that email address will then be exposed in certain links. An example would be the 'View User Profile' link:

https://www.<DOMAIN>/confluence/users/viewuserprofile.action?username=<FULL EMAIL ADDRESS>

The email address of the user is hidden in the page, but what good is it if the username (email address) is visible in the URL itself?

I do understand that users do not have to use their email address as a username, but why would Atlassian provide a 'Same as email' button when users sign up given this possibility?

Please address this issue and let me know what will be done to resolve this.

Thanks,
