Yes, same thing started happening here about two weeks ago. No idea if something has changed on Gmail side, like spam filter update, but reporting such messages as spam does nothing. I also fear that legit email messages containing important attachments from gmail.com domain might end up in spam after spam filter learns that "attachment = bad". Tried reporting few as phishing in hopes to get some attention, but that probably ain't doing anything at all.
