Hi there

I usually lurk, but today I have a question. Well, three actually. I run a blog dedicated to helping newbies, and finding freebies and good deals around SL. Yesterday I found two related places (different sims) that had a lot of great original content for free. Lots of really nice Japanese-created content, pretty skins, original newbie kits and the like.
One of the locations, though, was offering free shapes from well-known designers in SL. I don't own anything by these designers, but I do know the names, so before I blogged about these shapes I wanted to make sure they weren't ripped off.
Here's a pic:

As you can see, there are shapes by Blowpop, Naughty Designs, Minnu Model Skins, and Laqroki, among others. The boxes contain the shapes only. Most of the shapes inside the ad boxes bear the designer's names, except the two male Laqroki shapes, which are just called 'Aidan' and 'Cliff'. The pictures on the boxes show most of the models wearing demo skins.
First question: Are these shapes given away by the designers so their demo skins can be seen on a good shape?
Because if those shapes are modifiable, then someone could easily just note down the slider settings, recreate the shapes and then give them away. The place I saw them at isn't even selling them; they're freebies, and they're not trying to claim the shapes as their own (if they were, then I wouldn't know anyway; I couldn't look at a shape and say "that's from Laqroki"!)
Second question: If shapes given out like this are modifiable, then is copying the sliders and recreating them considered 'fair game', as long as the original creator is credited?
Third question: Should I blog about these shapes, or not? I certainly don't want to promote content that might be stolen, or considered as stolen.
Everything else in both areas I went to seems to be perfectly legitimate. I'm just concerned about the shapes.
Thanks for your help!
