Hi
I have a question regarding some thing I have seen happen on my Website.
Basically here is the scenario
A user has a gmail email address linked to his google + eg: [email protected], but when he registered on Facebook he/she used a work address eg: [email protected] now by the time they register on my site they moved to a new company but forgot to change their email.
So now what is happening is the person registers on my site using [email protected] which is fine, but now the next time they come back they click on login with "Facebook" the email is different so the system creates a new account, they come back again later and login with google+ again the email is different so the system creates a new account.
Eventually I am sitting with 5 accounts for one user assuming they use different email for each social network.
My Question is this.
How do I prevent this from happening
Or am I just going to need to continuously manually delete accounts
