Why ask such stupid questions? If someone can be deceived, then it isn't good, and a person cannot always know absolutely everything. There are simply no invulnerable people. But the point is that beginners do not know; they trust more when "someone pours into their ears." Beginners often trust people who, in their opinion, are ready to help but end up in the clutches of scammers. If you are skeptical enough, you should not even ask these questions, since you can be deceived here too, by saying something you do not expect to hear. In order not to be deceived, go yourself, study independently, and always look back. Have you been deceived? But seriously, a person has a brain that needs to analyze and only then make decisions. If knowledge is not enough, it needs to be supplemented and not rushed, which often happens to those who have been deceived.
