I think that department has already had a stroke.

For the last month or so, on a daily basis, I have been getting the same spam messages (subject line: "You've been chosen”) in my inbox, often classified as important. No amount of reporting them as spam seem to help.

However, what ended up in my spam folder are emails from Amazon informing me about winning $100 in their sweepstakes. (When I found them it was too late to claim the prize as confirmed by Amazon's rep.)

I get that spam is hard, but weighing an account owner's signals more than other signals seems like a good strategy. (And if it is not, please do correct me!)
