It depends on what you get picked up by. My ancient email address picks up all kinds of spam. I'm not sure where the Korean comes from at all. Nor am I sure why this particular woodworker thinks I am certain to buy their woodworking plans on the 842nd email when the first 841 haven't worked. I am a rather classical nerd on this point... not completely incompetent when it comes to home repair, but certainly not doing woodworking for fun on the weekends, and have no idea what signal I showed at any point that convinced someone the contrary might be true.
And then my wife has a completely different spray of spam. The amusing thing to me is that for both of us, while some of it is clearly a matter of what we're doing, she also has weird random stuff on those occasions I am tasked to find what happened to some email, and it's completely different weird random stuff.
I don't know what I did, but this election I've also been getting hammered by spam texts. I hadn't before. Not only that, it is as the author of this piece mentions, rather widely targeted. Messages that are clearly sent from the presumption that I agree with their politics despite very much not doing so... you know, the scare texts where they send "If you don't donate to us immediately the opponent is going to DO X IMMEDIATELY" and you're all like, my gosh, we should be so lucky that X would actually happen immediately but no, that's not actually going to happen. Clearly completely mistargeted. Which leads me to think even the ones I nominally wouldn't hate could well just be random luck too. And for me at least, this was a single change... from nothing last election to every single side and every shuckster trying to push poll me from every direction at once.
