When do you plan to do this, because I see you are still posting the same tired argument, months later.
Listen, truly: I get your frustration. I'm a semiretired PC tech who is still having to explain that Twitter/Facebook/MySpace/hotmail.com/Microsoft/AOL/usenet is NOT going to start charging per message, or get deleted, etc if people don't forward something to 18 friends, count to ten, say a prayer, and then watch something turn blue. But you need to let it go. Your "fix" is not feasible- some of us need to check the weather, or purchase things online, or check stocks, etc. Not going to a website with malicious advertisers works, of course, but you often don't know until it is too late, and then if you need that website anyway...
You can say apple has no part in this, & no way to fix it, but that's just incorrect. Aside from the enormous clout apple could bring to bear on webministrator's responsibility in vetting their advertisers, on my PC and android (which of course DO get these, as you've said), there are simple ways to stop it. Apple could provide us with similar tools, or offer methods to blacklist ad-servers like cloudfront.net before they take control of safari, with options to allow access IF needed. They just refuse to release their death grip on their precious OS, even at the cost of functionality. That is poor service, in spite of the many ways I will grudgingly admit that iOS is superior. My next phone will most likely not be a iPhone, simply because I am a power user that demands access and control of every aspect of my devices, even at the cost of having to learn how.
I'm just saying, man: give it up. You're helping to keep this thread alive by belligerence alone, and I assure you that is a quick path to burnout. You seem like a fairly knowledgeable (if annoyingly "appleogistic") person, and I might need your assistance one day for a problem with a real solution. Sit back in your knowledge, enjoy your non-use of sites that inject malware scripts, and let this thread wither. I just wasted an hour reading through useless "help", from people that know what they're talking about, all the way to those who think that they have pocket magic. Peace and quiet to you, sir. Especially the quiet. ;) (Sorry for the wall of text, but I was inspired by the plethora of tiny letters I just finished reading through.)
