Every one of those pages has citations to reliable secondary sources (if they don't, you can get them deleted by referring them to AfD). If you can provide sources for the person you want to write about, a source that includes some argument for their notability, your article will survive too.
It's frustrating, some of the pages that manage to survive on WP by dint of flimsy sources that have written about them. I spent a bunch of months trying to push back on spam pages in my own field on WP and ultimately gave up. But there's a reason it's like this: it's an all-volunteer project, and they have to draw a line somewhere, and it has to be a line that's easy for (very) part-time volunteers to quickly and cheaply adjudicate. WP:RS is exactly such a line.
