He lied about going on a dinner date with the CEO in person
Even if that's true, it doubt it influenced someone's decision to deposit Bitcoin to the scam site.
He was only concerned with his own selfish interests; he was paid
But he also paid campaigns out of his own pocket.
he failed to conduct basic research; I regard him as a person who is easily manipulated.
This I can agree with. Sometimes being paranoid pays off. That's why I've rejected most of the campaign offers I've received. I'm pretty sure some of them would have turned into a scam.
