It's his friend or have bought it
Do you have any evidence that it is a friend of Dooglus? I don't think it is okay to give your friend positive trust like that.
Its likely that the person has either no idea what he is talking about or is just posting to increase his post count for farming purposes. At any rate, about giving your friends Positive trust I think it is more or less allowed to give friends, which are people you trust hence the trusted feedback, and I have seen a hecka lot of people doing it too.
