I personally don't pay attention to where my links are going to be placed, but when I find out that something was done to block the spiders or whatever to deceive me, I make sure I let people know about it (not the blocking part, but the deception). I kind of rely on my instinct on the trustworthyness of a webmaster. And yes, I get burned, but it's saving me time and looking at the big picture, if works out better
