Honestly, at this point I assume my email and phone number have been exposed to so many people's insecure methods of storing them (recruiters, friends, family, coworkers) that they are essentially public domain.
Not that I want them to be, but such is life. I don't answer unrecognized phone calls, and my spam filter does a decent job. And where these could be used as login I try to use random passwords.
I got a warranty replacement for my phone a few weeks ago, and immediately noticed that despite explicitly signing in to SwiftKey and verifying that my member ID was the same across my devices, my new phone was not getting any of the dictionary suggestions from my old phone.
At the time I spent a couple hours googling it before giving up. Glad to see that my dictionary suggestions were instead going to someone else. I'm sure they'll be pleased with the variety of profanity that my years of texting should bring.
