Had it for a few years back then and never did anything bad or oblique with it, just used it as my secondary email account and also for deploying a small, harmless Chrome extension to the Chrome store.
So one day my wife bought a tablet and also registered a mandatory account. 1-2 days later my and her Google account was terminated. I mailed support and they told me they couldn't tell me the reason for terminating both accounts. No kidding. Tablet suddenly obsolete. All my emails gone.
Since then Google is a big red flag for me.
Addendum to clarify: They said they won't tell me the reason for terminating my account. I'm sure they could have told me if they wanted to.
