This is a major update by adsense as we know all about adsense is a famous publisher network and best source to make money online for bloggers.
Previous updates was also great peoples can add users into adsense account so all of writers and admin can see the stats.
But this time they made a big update you must will love it because as we also know about adsense they has very stick policy they ban account if they found and bad activity in your blog. So this time they made little bit changes now they only ban websites not completely account.
We got a mail about my one of blog http://technozan.com they wrote in mail this site ban in your account but account status is active as I shared a email screenshot below you can see it and read better and understand what I am try to say.
So I hope you may like this update my this post only this mean I want to just notify you that now no need to worry about adsense block status now policy is little bit changed now you can use one adsense on multiple sites and if site is not vulnerable for policy they will ban or block only a site.
