I haven't found this to be true at all. I've probably marked thousands of linkedin messages as spam, but they still land in my inbox occasionally. I also get random e-commerce related spam from sites I've never heard of. The false negative rate is massive on corporate spam that should be trivial to classify I'd think. e.g. some of them literally have some variation of "this is an advertisement" along with unsubscribe links.
