As a child who was raised in Scientology, I myself was not lured in through usual tactics. Scientology was basically all I knew. My parents were victims of these tactics and I was privy to many of the common ones that are used.
Scientology was designed by L. Ron Hubbard to infiltrate and dictate every aspect of a person's life. As you can imagine, if you were to present any problem you were having in your life to a Scientologist, they can open a book and show you what Hubbard said to do about that particular problem.
On the outside Scientology seems to have all the answers. For example, when you are stressed at work, Scientology tells you to "take a walk". When you are having trouble with a business Scientology gives you a series of steps to follow that is supposed to correct the area in which you are having trouble. This aspect of Scientology really is just glorified common sense.
