Yup. There's a reason for that. Spammers are trying to target idiots specifically. Normal intelligent people who would otherwise get tricked tend to be the type with the wherewithall to follow up with authorities. Idiots tend not to be.
I've also personally seen how "boring" and "ugly" web pages with lots of bold and italics and even underlines convert better than a trendier, "prettier" version. For non-spam, non-scam products.
