This makes it SUPER obvious when they're lying, for me. My profile, at the end, if you press "read more," specifically says no Amazon recruiters. None of them read it. Ever. Or if they did, they specifically overlook it and don't acknowledge it in their spam mail.
The funny thing is that I've had several smaller / more local recruiters comment on it and laugh. They get a small amount of respect / hold my attention longer than the first line of the email.
If it was less than once every two weeks, it wouldn't be such a problem. Heck, once in three months like in the article sounds like a huge improvement. They are seriously relentless.
