The first example is not indicative of the actual difficulty because the letters are pink (this is noted, but still). Beyond that, the examples use extremely hard to see letters... that completely defeats the purpose. There's no need if the challenging part for the computer is detecting satellite imagery. There are multiple letters on some of the images, sometimes hovering between two images. Again, why? The computer is going to have no problem divvying up the images, but the ambiguity is confusing for humans. Make the letters as easy to read as possible please. If that breaks your captcha, find a new captcha method.
