Increase and decrease on the spam-o-meter (Score 1)

Since about Sept. I've received about 50% more spam on my company account and about 10% of that is making its way through the spam filters (had a few this week already). So from that perspective I've seem an increase in spam. But my Yahoo account used to get 150+ a week in spam, that has trickled down to 10 or so. Gmail is the best with almost nothing, just a few and no adult or pron spam.
