I just like to share this Friendship-Auto-Follow-Script with you.

[sturmfink]

This file will enable automatic following for friendships (excluding Administrators).
Just put it somewhere and include it in your functions.php or your plugin
i.e. include('YOUR_FILE_PATH/bp-followers-auto-follow-friends.php');
(or copy and paste the code directly into your functions.php)

There are three Variations in here (A and B currently active):

A Automatically follow user when requesting a friendship with them
B Automatically follow user when accepting a friendship with them
C Automatically follow in both directions after a friendship is accepted

Varitions A and B obviously go well together :)
Variation C (currently commented out) should only be used singular

I hope this helps anyone:

-> Script

Have a beautiful day!
