In my eyes bigoole is a bigjoke.
It got a list of registred domain name and now is indexing all of these sites with an automated tool.
It does not care about quality of these sites. In
http://www.v7n.com/forums/597467-post22.html he posted some links so we all can see what is being indexed. These list are very usefull. I'm think of using them to improve our spamfilters as most of these sites will never be listed by a serious directory.
Just look at
http://www.bigoole.com/url1.php
an example
"www.a1homejob.com" reroutes to a deeplink of "job.com"
"www.a1homejob.net" reroutes to the same deeplink
"www.a1homejob.org" reroutes to the same deeplink
"www.a1homejobs.com" are you getting the picture
"www.a1homejobs.net" or do you need more
"www.a1homejobs.org" so you now have index 6 'sites' all wich are redirects to one page with almost no content (except for the advertisements)
You can find many examples like this just by browsing the 6 pages he provided url1 to url6
BTW bigoole is not a directoy at all as you can only use a search to find sites they indexed. We call such a thing "search engine" not "directory".
