Google adsense disabled?

I got adsense banned. This is not my issue. My question is, was there recently a new google algyrythm changes for adsense? I've notice this past week, a few others were getting banned more frequently than normally. Is there any news on the new info or any info about changes?

I know the traffic was bad but thats not my question. Was there anything released in news or info about a new algerythm or tons of people getting banned more than normal this week?
