More frequently, I've been taking to /dev/nulling entire domains for crap. Usually recruiters (no, I'm not interested in your underwater basketweaving SEO marketing position in south-west Obscuristan, it's well outside my search and skill parameters).

I haven't got around to writing a good set of whitelisting scripts, but that's next.

Figuring out if I've subscribed to something, and/or how to MAKE IT STAHHHP really isn't worth my time.
