XF 2.2 Dont register twice?

[Robert9]

Every day, some people try to register a second account.
Every day, a moderator deletes these registrations from the queue.

Is there any add-on that avoids registering when there is an account?
Avoid it at all to have less work.

This might be a bug, or what I would consider a bug, if XenForo is allowing multiple registrations into the queue with the same email address.

XenForo should not only be checking existing registrations, but also registrations awaiting approval, for duplicate email addresses. It sounds like this might not be happening.

XF does not allow multiple accounts with the same email address or user name.

My question is:
Can I avoid registering for people with an existing account?

1. New user => register link => register form => register

2. No new user => register link => new page with text:

Hey, we have found {username}, is this your account?
We don't allow multiple accounts without a special reason.
If you need help, you can write a message here => link to contact page

Another way could be to remove the link "register" at all and also stop /login/register from working.

Or we could have the login page with:

username: [username = existing user]
password: [no password, must be filled]
