"we think this is spam"
You have added a feature that doesn't dump potential spam into the spam folder but shows a yellow bar saying "We think this is spam" and then allowing us to say it's not spam or that it is. But if we say it is not spam, when the same sender sends something again (and again) you STILL think it's spam. C'mon, when I say it isn't spam, it isn't. Stop repeating the message over and over.
