This directory isn't badly indexed. But one problem with this directory in particular is that it has thousands of pages covering more than one country.
What matters more is how selective the directory is when it comes to accepting submissions, as well as where that TBPR 4 is coming from.
In this case, most are coming from link exchanges with other directories, footer links (http://www.cyprus-trader.com/search.aspx?cat=Sports+and+Leisure), and other crap links.
Does it rank for [real estate directory]? No, which makes me suspect many of the inbounds aren't being taken seriously by Google.
