Hi

instead using a link field type, use a normal text box and harcode the link to social account in the function. That way, the user has only to enter his account name and the link is build when the data is on front-end.

profile fields are stripped
profile datas are made clickable by default for search purpose in BP
We don’t want this for icons or when linking to a social network.

Here an usage example which use fontawesome to add the icons. That the general idea, change it to your need.

function bpfr_socialize_profile () {	

echo '<br>'; 

if ( $data = bp_get_profile_field_data( 'field=Twitter ' ) ) : 
?>

<a href="http://twitter.com/<?php echo xprofile_get_field_data( 'Twitter', bp_displayed_user_id() );?>/" target="_blank" title="Twitter"><i class="icon-twitter"></i><?php echo $data; ?></a>&nbsp;

<?php endif;

if ( $data = bp_get_profile_field_data( 'field=Facebook ' ) ) : 
?>

<a href="http://facebook.com/<?php echo xprofile_get_field_data( 'Facebook', bp_displayed_user_id() );?>/" target="_blank" title="Facebook"><i class="icon-facebook"></i><?php echo $data; ?></a>		

<?php		
endif;
}
add_filter( 'bp_before_member_header_meta', 'bpfr_socialize_profile' );

Take a look at DB tables related to xprofile:
_bp_xprofile_data
_bp_xprofile_fields
_bp_xprofile_groups
_bp_xprofile_meta

If users entered data like https://twitter.com/comandovictor use a mysql command to wipe out https://twitter.com/ via phpMyAdmin.

UPDATE table_name SET col_name = REPLACE(col_name, 'old_value', 'new_value');

wp_ is default table prefix, change it if you use another prefix.
UPDATE wp_bp_xprofile_data SET col_name = REPLACE(value, 'https://twitter.com/', '');

That’s the fastest method. Don’t forget to backup the table BEFORE doing this.

Changing the field type can be done from the xprofile admin.

@cybnet,

you’re right, i wrote link instead URL box.
Perhaps ongoing work around backbone by @imath can inspire you.
