For me, it's really hard, almost impossible, to believe these types of announcements. Most of the time I see an announcement like this, I instantly assume it's a scam unless it's getting promoted by the official page of a well-known company/firm or a personality. My brother entered in a giveaway for a smartphone from
degoogledirect.com last year. After a week, the giveaway ended, he found out that his personal data and his email got stolen because he introduced the necessary information when he registered for the giveaway. His friend and I warned him, as always he never listens.
