I created a snippet for easily removing ALL groups or individual groups from a user’s extended profile page on the admin. I extended the Member’s Stats widget to add the links.

Add this to the functions.php file:

/*--
Add Remove All Groups from Member Option
-------------*/
function bp_groups_profile_remove_groups( $args = '' ) {
	$r = bp_parse_args( $args, array(
		'before'  => '<li class="bp-groups-profile-stats">',
		'after'   => '</li>',
		'user_id' => bp_displayed_user_id(),
		'groups'  => 0,
		'output'  => ''
	), 'groups_get_profile_stats' );
	
	// display links to the groups a user is member of
	$group_ids = groups_get_user_groups( $r['user_id'] );
	
	echo '<li><a title="Remove ALL groups" href="' . wp_nonce_url( admin_url( 'users.php?page=bp-profile-edit&user_id='. $r['user_id'] .'&remove_group=all' ) ).'">Remove ALL Groups</a></li>';
	
	foreach($group_ids["groups"] as $group_id) { 
		echo '<li><a title="Remove group" href="' . wp_nonce_url( admin_url( 'users.php?page=bp-profile-edit&user_id='. $r['user_id'] .'&remove_group='.$group_id ) ).'"> Remove: ' . groups_get_group(array( 'group_id' => $group_id )) -> name .'</a></li>';
	}

}
add_action( 'bp_members_admin_user_stats', 'bp_groups_profile_remove_groups', 11, 1 );

function bp_remove_groups_from_member() {
 
    if( isset( $_GET['remove_group'] ) ) {
 
        $user_id = isset( $_GET['user_id'] ) ? $_GET['user_id'] : 0;
		if ($user_id == 0){ return; }
		
		$group_id = $_GET['remove_group'];
		
		if( $group_id == 'all' ){
			
			//Find Member groups and remove all
			$group_ids = groups_get_user_groups( $user_id );
			foreach($group_ids["groups"] as $group_id) { 
				groups_remove_member( $user_id, $group_id );
			}	
			
		}else {
			
			//Remove Single Group
			groups_remove_member( $user_id, $group_id );
			
		}
 
    }
}
add_action( 'bp_members_admin_load', 'bp_remove_groups_from_member' );

Enjoy.
