My sense is that it's just a good way to annoy people whose job isn't hiring. At best, you're risking annoying someone who is busy (and your email being deleted with no reply), at worst, you're actively penalizing yourself if you are demonstrating that you aren't willing to go through the standard hiring process that the company uses. (For other terrible ways that job applicants try to "stand out", Ask A Manager is a veritable goldmine[0]).
