If a site has very few links say less than 10 and PR is 0. But the domain name is 6 years old. If you submit to 1,000 directory will google penalise it, remember it is 6 years old domain and has been parked most of its life.
You can buy like 500 directory submissions for like $50 and stuff like that but I have tested these things on sites that I am not bothered about and it doesn't do the sites any favours, you should do all of the submissions yourself and as previously stated use diffrent link titles and descriptions.
