Why are my link pages not being indexed?

Question

I tried something but it didn't work. Iwill try to explain what I tried to do and probably someone could suggest what can be done.

I have a few websites, about 75, all in the same niche (travel).

I created a link directory sort of pages and uploaded all the pages (about 17 pages with about 10 links in each page) and uploaded the same pages to about 30 domains to see what kind of results I get.

I also created a separate sitemap for the links and uploaded in each of the domains.

I have waited close to two months now.

All the other pages of my website, let's say above 98% of the other pages, are indexed but for my link pages.

Any ideas as to why the pages are not being indexed?

I am thinking of adding bit more of data in each of the pages so that it doesn't look like just a link page. Would that work?

All your suggestions and inputs are appreciated.

Google is wise to inter-linking sites owned by one person/business (or even beyond that), and it will hurt you (if it hasn't already).

Also, what extension are the domains you own? If they're .info they may still be affected by Google's penalty due to the large amount of spam .info domains that popped up a while back due to how cheap they are. If I remember correctly, .info domains younger than 6 months old may not appear in SERPS.
