Some users may want to spam or cheat in my game by creating many user accounts with fake email addresses. I need to be able to prevent this. Therefore...
I know App42 User Service has userService.authenticate(), But this a check for when the user wants to use a service, or log in. But when a user first creates a user account and enters his email, how can I send an email to the email address he just entererd, and in the body of that sent email is a link that the user has to click to show that he is indeed the owner of that email address?
