Probably because it is a big company, and that's why they got scammed. Honestly, a lot of people out there would fall into a scam just by attaching the name of big companies like Google, Apple, etc., to their promos and everyone would literally fall for it. Just look at how a few people in social media share articles that indicate "Free giveaways" from a page that doesn't really seem legit, but they still try it since they have nothing to lose.
Wow this was kind of an enlightenment to me. I kind of realized that the scammed was also at fault here, not just by falling into a stupid scam attempt by the other party, but by also trying to take advantage of the opportunity. I'm not saying that it's not right to take the chance when it's there, but really, it's like both sides are at fault here, first is that the scammer took the opportunity to rely on a big name to make money, and the other is that the scammed tried to take the opportunity to rely on that scam to get rich ( which obviously backfired ).
