    Within the current technology scenario, social networks have become a premise to be included in society. we see more and more as our information is needed by the web. This information supports a gigantic market of embezzlement, fraud and scams. But this is something that society with the immersion in technology ends up getting used to. I think differently. Since the possibilite of this information is acquired, why not use it in a way that also helps the user? Imagine that, I'll use a personal example, you have information that such user has been watching your streaming platform in an "abnormal" way, for a long period, several hours per day. I cannot say precisely, of course, because it is undoubtedly not my area, but because I have a diagnosis that leads me to take such attitudes, coincide with the example. Yes, I suffer from depression, and that world which should suppose to help us, are leading us to a total wrong way. I really belive if we won't start doing this now, we're helping those in charge, to rule above all our next generations.
