That does make sense, it sounds counter intuitive the first time you hear it (like when you hear about the 'which prize door to pick' scenario the first time),

That does make sense, it sounds counter intuitive the first time you hear it (like when you hear about the 'which prize door to pick' scenario the first time), but then sit and think over it and it starts to click. To most of us with very little experience as scammers, trying to spray-and-pray our way to riches makes the most sense. But to people with experience, adding those location cues and grammatical errors is their tool at reaching their target audience. To us as receivers it makes no sense because we are expecting communications to be a certain way and for people we communicate with to be within a certain 'internet sphere' of knowledge and current trends (another example, some companies you deal with in some countries still send passwords over email, in my country many companies don't even put links in emails, just tell you to go to the website). So we've filtered ourselves out.
