I just signed up via G+ (I may be mistaken, but can't everyone with a Gmail account signin using g+ ?) Did not get any message about email address conflicts
Edit: Just tried signing up with Facebook (which has one of my other email addresses on file), still no message about email address conflicts, signed up and logged me with no issue.
Tried signing up for another account with GitHub and did get a message about email or username conflict this time, but I was using the same email address on G+ as Github so it was a legitimate conflict.
