Requesting Read-Only user activity stream

We've been trying to figure out what to do with the guest access-level Social page. After much debate with the team, we decided the best option for our site is going to be to make a custom profile, controlled, updated, and etc, by moderators and admins only. We want this profile to be able to send and receive friend requests, follow users, and the such. We also want this user's activity stream (including but not limited to all affiliated posts) as a read-only activity stream for all guest users as a sort of targeted advertisement of popular/preferred social accounts. Is anyone able to explain how, give us a rough-draft of such a feature, or provide any links directing us to procedures to manually add this?

We may also be looking to make the social profile optionally indifferent to the account, so users don't "have" to have one, but this is just an off-note feature I felt like adding in case you had input.
