I opened a single Adsense account in 2017 and have never created ads with it, just wanted to understand the process and keep it ready in case I need it some day. Today they sent me this email:Hello,This email is to alert you that your publisher account (Publisher Code: pub-923XXXXXXXXXXXXX) was found to be non-compliant with the AdSense program policies and as a result, it has been disabled.
