Unless you’ve been living under a rock this week, you have probably about how Google is further degrading our privacy and letting people who don’t have your email address email you. Then over the weekend I received an email from Google about the change. The email was a good reminder for me to change my settings, but wasn’t particularly helpful in how to change the settings.
So I went and logged in the “Who can email you via your Google+ profile?” setting from “Circles” to “No one”. I’d recommend you do the same if you’re on Google+, which is probably the case if you’re reading this post.
