BuddyPress.org

For those still looking for a solution to this, you can add the following code to the functions.php file of your active theme. The username gets replaced with the username you wish to hide. Alternatively, you could substitute the stuff in the parens of the conditional with a properly done current_user_can() statement to hide all the administrators.

`
global $current_user;
get_currentuserinfo();

if( $current_user->user_login == ‘username’ ) {
remove_action(“wp_head”,”bp_core_record_activity”);
}
`
