You know what never ceases to amaze me is the credit that people give google. You act like they're this omnipitent being ready to strike the second there's and in justice. Well people google is VERY easy to game. That's the bottom line. If you're looking to build a big whitehat brand name site then no don't do something like this. If you're looking for a "disposable strategy" then this might be right up your alley.
People ask me all the time what if I get banned? SO WHAT! If you're gaming the system and making a profit cool. There's a lot of ways to skin a cat as the old saying goes. And any good blackhatter knows nothing lasts forever so the good ones that stick around are the ones that have a lot of projects going at once. Then if one dies it's just like a PPC campaign dying you usually have others in place.
So STOP giving google and yahoo so much credit they really don't deserve it.
P.S. Don't be a dumb ass and say well I have my 2 year old whitehat site I've been working on forever and ranked and now it's banned, to me. That's NOT what this is for, it's a disposable strategy. You've been warned.
