I’m afraid this plugin itself doesn’t have the function to add messages in the activity stream.

After six hours of labour, I have finally figured out how to add the function as a separate plugin. There are two hooks, bp_follow_start_following and bp_follow_stop_following, for such a purpose. So we can write a plugin using these hooks, theoretically. But here is another problem. In BP Followers 1.1, these hooks don’t work, causing runtime errors, because of lacking array() in a do_action_ref_array() argument. Perhaps it can be fixed soon, and we can write a plugin to display follow/unfollow messages in the activity stream.

Thank you for fixing!
I’m now writing a code to inject follow/unfollow messages into the activity steram, using bp_activity_add() function.
