There was no handbook to sign. Nothing you typed was recorded, and nobody is in trouble.
Do this now — one minute
Change your password at myaccount.google.com/security. Not because we kept it — we didn't — but the habit is worth having.
Confirm 2-Step Verification is on while you're there.
Three things gave it away
The sender wasn't Bob.Real Bob mail comes from no-reply@hibob.com. This came from noreply@earthrated.com — and Front shows the address right beside the name, so it was on screen the whole time. The bold name is where your eye goes; the address next to it is the part that can't be faked.
hibob.com was just a subdomain we made up. The owner is always the last two labels — so read URLs right to left.
It wasn't accounts.google.com.And here's the catch: earthratedpoopbags.comreally is ours. So "is this an Earth Rated domain?" was the wrong question — it would have reassured you. Google sign-in happens at accounts.google.com and nowhere else, ours included.
The one rule
Never sign in through an email link. Open a new tab and go to the site yourself.
That single habit defeats all three tricks above, and you don't have to inspect anything to use it.
