Yup, I was just working on implementation a Twitter login, then realize it would not return an email address… So I can’t compare that login and control double account creation ( 1 per email address ), so it’s worthless.
Twitter login will not be implemented. Will only be possible to link a twitter account if a facebook, google or custom account was made created prior to use any twitter features.
As for the “twitter is not linked to identity”, well email address either. I don’t see why providing an email address would be considered as linking an entity to a twitter account.
You know how many emails I have ? Lots. Yet, believe it or not, I’m just a single human.
