2) for FB marketing, it doesn't matter if you buy those likes from FB or a farm, the distinction in terms of effectiveness is whether they are bought v not bought.
Agree, I think. You can buy them from FB, and they can still be crap. That's my main objection to the "legitimate" versus "non-legitimate" talk. A discussion of the varying levels of "fake" would probably be more useful.
Buying likes from facebook doesn't somehow make them a responsive marketing list. On top of that, even a great list would lose money in the hands of the wrong person.
