There is Daemonlinks admittedly either owned by 'The Freemasons' Or 'The Illuminati'. It's a British Search Engine combined with an ODP based Web Directory.

I add my blog sites and it feeds me some high quality traffic - however with regard to Google there are some interesting side effects (I get additional keywords, keyword boost and pagerank boost

I've now been told it's 'Age based Authority' by several people with no clear definition - could someone please enlighten me?

Do entries (backlinks) on a Free Web Directory cause any issue with Google Adsense?
