I hope you are still monitoring this post. As marginal as the value of reciprocal links are, they are not worthless.

Far better advice would be to individually evaluate each request for a reciprocal link. Summarily dismissing reciprocal link requests from someone who uses a scripted application to automate their reciprocal links pages will keep you from forming partnerships with those who use good SEO practices, and would help you get inbound links.

If the site makes reciprocal links only with other real estate sites or related businesses, home inspectors, appraisers, movers etc., it will not hurt to link with them.
