I am running Xenforo 1.4.3. I have had some members getting a message about being on a BlackList (see photo below). These are well known members, so we can safely say that these are false positives. They have been members of the forum for years, so this is not related to the sign up process. They get the error browsing the forum while logged in.
What is causing these messages? (I only see blacklists mentioned related to the signup process) ...and how can I avoid these false positives for already signed up members?
Edit: I used to have the "TAC De-Dos - Reduce the effect DOS attacks usually caused by spam bots" plugin activated.. it has now been deactivated. Not sure if this is relevant.
