Not really any change. I just checked, and from about a month of spam, there were maybe 2 messages (semi-junk from web sites that I wouldn't really miss) out of 110. I usually do check (though not necessarily empty) the spam more frequently. I am not sure of the details of Google's spam ranking algorithm. The opposite thing: what if spammers marked everything in their spam box as "not spam" ? Actually, I don't think spam needs to do this. It already is using an extremely efficient natural-selection tool: the human brain. You could just be a victim of a slight variation in the changing spam entropy, as some type of message similar to your emails becomes more spammy. Without a tool to show the actual scores of messages, asking here is probably the best you can do. (If there was a tool, it would only encourage gaming the system more.)
