I don't get much more spam, but there is one obvious spam message that gets inboxed often, even though I've flagged it as Spam and Phishing damn near every time. It is one of those fake UPS messages that there was a package left there unsigned and you have to pick it up. Only instead of UPS, their logo is IPS (for International Parcel Service), which as far as I know, doesn't actually exist. I've been receiving that specific one with different fake tracking numbers every few days for well over a year now. You can bet the spammer/phisher is a paying Google advertiser... that is the only reason I can think of for its overall longevity.
