because there's no unsubscribe. i went through a few recruiting agencies 5 years ago to get a job and now that my contact info is in all these recruiter databases, i get emails and/or phone calls almost daily. Even if I tell one recruiter I'm not interested, there will be a different one bothering me tomorrow. The worst part is that many of them are contacting me about jobs in a city that I don't even live in anymore.
