Black hat SEO, according to my knowledge, is not an official way of SEO. Just imagine that one day Google, Youtube, Facebook,...or any other traffic sources update their algorithms to a pain-in-the-ass levels, then there is no way (or hard way) for blackhatters to do SEO. The algorithm is only a typical example, there should be more than one reason making black hat SEO die....sooner or later. Just wonder how long does it take to make this story come true...
It will never come true.
No profession that operates just below the skin of the law has ever completely "gone" unless the entire purpose for its existence was removed.
In this case Google is not the law, they just have a preferred way of ordering their "for profit" directory or index of other sites.
All SEO is effectively black hat. Marketing is ok, but as soon as you create a link for the purposes of just creating a link - you've crossed the line.
Fact is marketing for SEO (rather than traffic generation) just plain does not work.
Unless you are a massive corporation, then subverting the rules is the only way to rank. But then of course this is not a black and while topic.
Creating a few extra links. Putting out some link bait content. Commenting in a few more places than would really be required? Well that's one end of the spectrum.
Peeling off 4 Xrumer instances to create 1 million 2 hundred thousand links a day by spamming the crap out of everything...that's different altogether.
But no industry that exists does not have an underbelly. From politics, banking, the military, dog breeding, TV and media, car sales, holidays, beauty products, sport, pensions,... hell I can't think of any industry that doesn't have an underbelly - and perversely the following is true.
THE TIGHTER THE RULES THE EASIER THEY ARE TO FIDDLE
Tight rules are rarely flexible or effective. They penalize the innocent (negative SEO is an example) and leave the space open for Trojan Horse methods to work. If done commercially they often breed a growing discontent by all users (not just those looking to subvert the rules)
Over-tight rules - tall poppy syndrome and a major corporation acting like a monopoly in a marketplace that is certainly NOT a monopoly?
Anyone else see how that will probably end?
