Honestly, I'm not clear what your point is. Are you saying: 1) Racists should put up signs that say, "Coloreds need not apply?" Because that will save you time from applying there (if you were Black). or 2) They should put up a sign that says, "If you haven't worn sunscreen in the past decade, you need not apply?" That way they effectively screen out Black people w/o having to seem racist. or 3) They shouldn't say anthing, and presumably waste your time applying? (This seems to clearly not be what you're saying, but I through it in there for completeness). Have I missed an alternative? In any case, regarding discrimination cases, there are plenty that are actually won by employees. While you'd like to think racists and sexists are smart enough to at least keep their mouth shut, enough of them apparently aren't so. I haven't seen a lot of race based discrimination in the tech industry (what I have is usually against Asian/Indians), but I've seen a LOT of sex discrimination. I've even written an affidavit on behalf of a woman, based on discussions I had during annual review with her manager. So yes, it is hard to prove. And if they were smart, nearly impossible. But still doesn't mean the laws should be off the books or ignored.
