I will take one vouch with pleasure
Honest review: Not worth.
It's one page text. All major ad network will tread it as a cheat and most probably your account will be banned.
With AdSense 100% you will get ban. Sorry melia, but this is the real deal about this so called tutorial. You may not get caught by Ad Networks, but only if we were 1999-2000. They are not eating green grass.
