Google + will help with seo, especially on Google as they see it as a quality metric ( how can they say their own product isn't a serious platform lol ? ), the same as Facebook is seen too as being a major player that adds credibility.
If you are able to ' jack ' these friends and they are from active accounts / users, then this would be a great addition. If you are just going to add newly created accounts, the benefit will be very little.
I have a website that get a few spot in the SERP only by adding a google+ plugin (from a BSO here in the forum). I am getting around 1-5 + per day and each week it seem that my ranking get higher. I believe that this is causing by the plugin since no-SEO is done on that site appart the initial on-page last year. If your tools can help generate more +1 then I guess this can help your traffic.
Google plus definitely has a major role in SEO, i've seen sites, videos ranked just by them, but i think its safer when you combine them with other signals.
will add option
1: when ids are processed it will auto save so when new ids are leeched it will be compared then remove only the ids that was used before so its not processing same ids.
