The occasional emails without the 5 points have been around for a while, I believe. They're always either BMG, MyPoints Games or the "7,000 points" sign up emails.

Still, I've noticed mine posting exactly as they have before. Last week I had 27 5-point emails, 2 10-point survey non-qualifiers, 1 25-point email sign-up and 1 50-point email sign-up, for a total of 230 points in a week for doing pretty much nothing. I don't think they've gotten stingy...
