We'll just have to see. Considering that I provide links back to the original garments (for folks to buy if they wish), there's really nothing I'm doing that any fashion blogger isn't doing. But it's a valid point you raise. I can totally justify MTL because it's not about mass producing rip-offs. Steal this look features, I believe, are far more offensive -- encouraging folks to buy cheaper knock-offs of designer garments.
I read a little about the Ana White incident. She chose to remove the images herself to avoid any headaches. Tech folks weighed in that she was in "fair use" limits. I would think that TSW would be protected as well.
Since this is a sewing community geared toward people sewing for themselves, there is no encouragement for mass marketing/reproducing. You aren't breaking any laws on the USA side.
I will say one thing its made me do is look at patterns I would never have given a second thought to previously, all because of the technical drawings.
