Doing no harm is not a reason to include the links and being useful is not a reason to include the links We err on the side of not including links in these situations The main reasoning that keeps coming forward about including the links seems to be WP ILIKEIT and WP USEFUL But after getting several neutral admins to contribute to the discussion the huge majority agree that keeping these links is inappropriate Unless someone comes up with some new compelling reason why these links should be included we all need to move on to something more productive IMO
