Email addresses use gmail, hotmail and yahoo

Hi!

Just thought to share some feedback on this plugin. When you generate users, it works wells but the only concern I have is that the email addresses use gmail.com, hotmail.com and yahoo.com.

There’s a chance that your generator actually creates a valid email address that exists – it also doesn’t match the username of the user.

I think it’d be best to use the username as part of the email and just use the site’s domain or something like <<username>>@fakeemail.local. I don’t see use cases where you’d need an actual valid email for dummy data.
