Hi, So I have around 35 different Facebook accounts, a mixture of aged and non aged, each account runs adverts in between 40 - 140 different groups per day. I am using Ninja Blaster. There are 9 different adverts that run in these accounts, with only 2 accounts running the same advert each day. I don't include any URL or link in the posts, just text and an image. I have been doing this for around two years I have the occasional issue but not often. However recently I will get the following message across the majority of my accounts in the space of an hour or so, not always just the ones that are running the ads at that time. "Your account has been temporarily locked We’ve detected suspicious activity on your Facebook account and have temporarily locked it as a security precaution. It’s likely that your account was compromised as a result of entering your password on a website designed to look like Facebook. This type of attack is known as phishing. http://www.facebook.com/help/166863010078512 in the Help Center. Over the next few steps we’ll walk you through a security check to help secure your account, and let you log back in." Sometimes it will ask for a phone code, each account is phone verified, or sometimes it will ask me to identify friends. However it will cause all my adverts to fail for the day. I also have around 10 other Facebook accounts that are used for another business that do essentially the same thing just for a different businesses however these never flag. These accounts all have their own individual adverts. I am desperate for a solution to this, or even an indication as to why these accounts flag.
