So if there is an adverse reaction that affects a certain group like young men or pregnant woman, the information will simply be purged from Facebook. The problem will still exist, it just won’t be acknowledged.
If you suffer with the problem, you will suffer alone and the problem will not be addressed or corrected.
Sounds like science to me.
And you will be socially ostracized for complaining about your problem that is unacceptable to talk about and in fact "doesn't exist."
