Hey there CalModels
Consensus = "An opinion or position reached by a group as a whole" Yep, it's a word!
As to your questions;
I haven't looked at your site CalModels...so not sure about that one. But, generally even with 'free' join sites...the surfer is still required to join the site. My general rule of thumb is...if the surfer is required to 'join' the site...it's a paysite...and links to that site should be non blind.
In the case of your site, it shouldn't be a big deal to mention the site name in your links...might even be better for you se wise. "Free Lingerie Models at Cal Models" got a nice ring to it even
I'm not sure how other reviewers handle the domain root hub links. For myself and most of my submitters, again...most folks do mention the site name in the link. In your specific example, if those are all paysite tour links...I'd say you'd be pushing it. After all, yes the tours are free...but to get anything good...the surfer has to 'join'. Damn, there's that 'join' thang again
Now, if you had a page of sponsor hosted free sites and/or galleries there...then you've got some free stuff for the surfer. A 'More Free Porn Links' link to that kind of content would probably be acceptable.
I don't think linking your copyright to the root would really be considered blind. But, it would definitely be included in the 3 outbound links rule of most link sites.
