What domain to use for free site....same one, different ones??

[mrenaud]

Should I be submitting free sites under a domain that I want to be a hub?

For examples my first site

http://www.adultpornos.net/freesite1/warning.html

is using www.adultpornos.net

Should I use this domain for all the free sites I'm going to submit?

I personally use a domain based on niche but it doesn't matter that much either way other than if you use one domain only you have a better chance at building traffic to that one domain.

I always thought you were supposed to submit from the same domain all the time. But yes, for the sake of ease, I would submit from a domain you intend to use as a hub. It might also help a bit with SERP's if there is actual content on the domain ( free sites ).
