I noticed that with some of my images, the watermark does nothing to protect the image. It's centered in the middle of the image, so with icon's or sets, the watermark doesn't 'touch' the subject matter. Especially with the large previews of Thinkstock, my images can easily be manually edited to remove the watermark.
I strongly advise Thinkstock to update their watermark by either tiling it, or extending it to the corners and side of the image.
