I have noticed the following things about tasteless tactics: 1) they're often horrifically effective; 2) people with taste will pronounce that they're ineffective without providing any evidence.
Pretty much anything than mentioned being a "ninja" or a "rockstar" was ignored immediately, and there were a few others I discarded out of hand, too for similar reasons.
Other than that, I'd just like to echo the point about responsiveness. There was one company I'd have loved to have worked whose job description I fit very well, but they took almost three weeks to respond to my application, and by then I'd already had an offer I really liked and I'd already written them off completely. There were a couple of others that said to bug them if I hadn't heard back in a while, and I mostly just stopped paying attention to those too.
In looking for a place I'd like to work I look for ads that say they understand what I'd be doing.
Also, there are two ways of asking for everything under the sun. The first, which rockstar/ninja companies ask for, is "7+ years Java, 3+ using ANT, 5+ in etc". You can never satisfy the requirements of this kind so they only get scammers or the truly naive who qualify but only because they once did all that stuff 10+ years ago.
The second way, which hacker companies use, is to say "We use X, and do hard-thing-Y in it. If this is your speed, join us. Bonus points for things we don't know about." These are not only clear and precise to the people they want but easily lend themselves to entrance interviews.
Also, horrifically effective sounds actually like a bad thing. As in, they're incredibly effective at getting an obscene amount of poor job candidates that it's horrifying.
