I understand the complexity. I actually just found you at 3am on Sunday morning
so I am very interested in the social syndication.
If there was a way to allow the creation that is completely hands off, that would be fantastic. From my understanding (anyone out there please correct me where I am wrong), when signing up for a social account, typically they ask if you would like to add all friends in your email account. When signing up for an email account, if there could be a central database of emails that could be uploaded into the account and throttled, this would send out emails to each person in the email contact lists asking if they would like to be your friend and join your network.
Then if the software could periodically login (once a month) to confirm the email links, I think this could be the answer. I'm sure it's much more complex that this on a programmer level, but I feel this would be the final step in avoiding the spam filter.
Look forward to growing the software with you!
