Unfortunately, when people feel like they're getting their big break by stumbling upon a lot of money or "winning" a lot of money they tend to forget basic security measures. I've done it in the past, and I'm sure there's plenty of stories like this. Fortunately, I clocked on before losing anything, and I don't think I would've lost anything, but people that aren't quite as aware might easily fall for things like this.

Another thing; unfortunately on social medias Bitcoin thefts tend to be treated as a joke, as we're still trying to escape the idea of cryptocurrencies, and therefore Bitcoin being fake money. We're still sort of combating against that stigma.
