Improved version, Update for BuddyPress 1.8.1 and WordPress 3.8

1. Replace your whole filters-bp-functions.php with this code:

<?php

// Turns on manual linking using curly brackets: {search-term}
function bcp_add_brackets( $field_value ) {
	// We use curly brackets instead of square to prevent possible conflicts with bbcodes...
	if ( strpos( $field_value, '{' ) | strpos( $field_value, '}' ) ) {
		while ( strpos( $field_value, '}') ) {
			$open_delin_pos = strpos( $field_value, '{' );
			$close_delin_pos = strpos( $field_value, '}' );
			$field_value =  substr($field_value, 0, $open_delin_pos) . '<a href="' . site_url( BP_MEMBERS_SLUG ) . '/?s=' . substr($field_value, $open_delin_pos+1, $close_delin_pos - $open_delin_pos - 1) . '">' . substr($field_value, $open_delin_pos+1, $close_delin_pos - $open_delin_pos - 1) . '</a>' . substr($field_value, $close_delin_pos+1);
		}
	}

	return $field_value;
}
add_filter( 'bp_get_the_profile_field_value', 'bcp_add_brackets', 999, 1 );

// Adds social networking links

// Checks to see if we can allow bbcode and if so applies it, otherwise leaves field unchanged
function bcp_check_safe_shortcodes( $field_value ) {
	if (function_exists('bbp_whitelist_do_shortcode')) {
		$field_value = bbp_whitelist_do_shortcode($field_value);
	}

	return $field_value;
}
add_filter( 'bp_get_the_profile_field_value', 'bcp_check_safe_shortcodes', 998, 1 );

function cpfb_add_social_networking_links( $field_value ) {
	global $bp, $social_networking_fields;

	$bp_this_field_name = bp_get_the_profile_field_name();

	if ( isset ( $social_networking_fields[$bp_this_field_name] ) ) {
		$sp = strpos ( $field_value, $social_networking_fields[$bp_this_field_name] );
		if ( $sp === false ) {
			$url = str_replace( '***', strip_tags( $field_value ), $social_networking_fields[$bp_this_field_name] );
			}
		echo '<a href="https://' . $url . '">' . $field_value . '</a>';

	} else {

	return $field_value; }
}
add_filter( 'bp_get_the_profile_field_value', 'cpfb_add_social_networking_links', 1 );

?>

2. Add the following class to the stylesheet of your activated theme:

td.data a[href$="members/?s"] {
	display: none !important;
	visibility: hidden !hidden;
}

In case you use a highly customized theme for BuddyPress or another Permalink, you might have to customize the CSS Code.

Have fun!
