These days "report spam" doesn't seem to do anything. I've gotten as many as five identical e-mails from the same sender and hit "report spam" on each one with no effect before eventually creating a custom filter rule to stop it.

Speaking of which, I went years without getting scam spam in my inbox (not counting marketing emails I never signed up for). In the last year or so some spam does make it through the filters into my inbox.

There's typos, unverified domain, big warning and all that, but gmail still thinks I'm interested in buying amazon gift cards in bulk. What changed?

UPS won't let me unsubscribe from their emails and I have hit "Report Spam" in Google Mail on hundreds of them. It does nothing.

I think you, as the GP, fall victim here of the approach of data analysis by Google. They probably have some analysis analyzing all users' spam markings and since too many other users do not mark it as spam, your marking does not weigh in much. You basically don't train the model enough. Just guessing though.

While some businesses may ignore FBL's and abuse complaints, most still handle them. Report spam definitely does something.
