Logically from the activity of the account you would see that he is not, and can not involved himself in all discussion because as Son of Donald Trump, there could be other important things he would place priorities and not to come here to start phishing for peanuts from innocent people.

But then, we must not trust people with our funds be it new start projects or any person who comes up with a famous or influential person's name and we think such person would have that time to involved themselves in most of the discussions here then is fake.

For instance, I can take Divido (OBO) and if an account is created with that username and he doesn't post according to his line of business or talks about music then we can say such person is an imposter trying to impersonate someone that he is not and for that we should be extremely mindful associating any business deal with them.
