We had a reduction last month and questioned them about it. Maybe they took ours out in advance this time. I'm guessing this should be the last reduction since they implemented their new program.
There has been a significant drop in overall earnings per day towards the end of the month. (I've been watching last months report to see when & how things were deducted (clicks, views etc) but don't have anything to compare it to this month because they didn't change the total. Not that I am complaining :)
