Do you ever open unsolicited press releases?
Yes, all the time. Unfortunately, most of them are useless because they're about subjects that our site doesn't cover. (Fictitious examples: Press releases about guinea pigs, iguanas, and parakeets sent to the editor of a site named for-dog-owners-only.com.)
But that's really beside the point. Google's guidelines are clear; you can respect or ignore them, depending on how much you care about organic search traffic from Google.
