About curezone users who are cured

Have you guys noted the cycle of the cured guys? In the begining they are asking for help, posting asking for advice, after they start to answer a lot of question and after they simple vanish... All those that i have been reading have the same patterns

1- ask for help
2 - help some
3- vanish and never enter here at curezone anymore. ( some didn t post a testimonial)

What you guys opinions about that? I think that is why we have so little post of sucessful stories...
