So as a previous Premium Publisher, I say "previous" because I sent my most recent account manager a certified letter indicating that I had pulled all my AdSense ads and wanted to be removed from the program within 30 days. By "removed" I mean no longer contacted about anything "AdSense" related via email, phone,mail. I also requested that my site no longer be listed in the Premium Publisher directory that is an internal document and marketing collateral to recruit other Premium Publishers.
Well today, against my wishes, I was contacted via phone and then email about a Premium Publisher "winback" offer they'd like me to consider. Essentially it's a guaranteed CPM deal based on my average mobile RPM earned in 2015. I mention this because if you are a Premium Publisher and have recently removed a majority/all of your ads, be on the lookout to hear about a similar offer. Desperate times folks.
