Well i see tons of posts online of people being blocked out of their accounts (like i was, just kept looping back to the homepage when trying to log in) - i think BING Messed up and had a hack to be honest, or they messed up their system somehow.. but this is the default message they are posting on a LIVE chat session i had: Hope this help.... Chris: After a routine review of your Bing Ads account, we identified possible unauthorized account activity.To best protect your information, we have closed your Bing Ads account. With your account closure, any active campaigns associated with this account have stopped serving. Chris: From our review, we believe your account may have been accessed by a third party to create online advertising without your permission. It is likely the third party obtained your personal account information elsewhere, and used it to access your Bing Ads account. Chris: If this third party did access your account, they would not have been able to view your full credit card number(s) as credit card numbers are never displayed in full within Bing Ads. Chris: Your account may be recoverable. We would be happy to help you restore your existing account or start over by setting up a new Bing Ads account, whichever option you prefer.
