Yup, I've had the same thing. Just kinda amusing and ironic since I didn't happen to care about that event but it makes one nervous about relying on spam filtering.
On the other hand, once you train it a bit, it is mostly remarkable good. For me, switching from fastmail.fm (which was pretty good itself) to Gmail gave me a big improvement in spam control.
Super curious about this response saying on gmail you have more control, because from where I am the “mark as spam” button does nothing but move things to the spam folder. In theory it should learn from that but when someone used my email address to sign up for AT&T no amount of marking things as spam will stop their emails landing in my inbox.
As in signed up for AT&T service? If so it's because it's not spam - it's misdirected mail, but there are tens of thousands of other Gmail users who think that messages almost identical to those are things they absolutely want to receive.
