I think that FB has a tiered system that flags accounts according to how spammy they look or have the potential to be. I also think that this algorithm is constantly changing on its own and evolving based on previous and current data. If this is true, an account that has any data on the profile that may have been flagged in the past(by you or others) might be penalized accordingly in their tiered system(not always an outright ban but rate limit's and filtering). What I would recommend is to put all of the accounts on a cool down and start doing things as organically as possible for a week or so. Give the profiles some credibility by not advertising at all and only doing things that normal people would do on a normal fb profile(no mass advertising,mass adding friends,posting excessively etc). Also post some ORIGINAL content and pictures. Hopefully that will lift any sort of restriction or bias that FB is imposing on your accounts. IMO the best way to approach advertising with minimal risk on fb is to assume that they have a massive database and they store any and all information that anyone submits to potentially use it for anti-spam measures. Meaning url's,ip's,emails,pictures, and anything that FB is able to obtain will all be integrated and cross referenced accordingly to strengthen FB's anti spam system(proactive AND reactive).
This is all theory but i've had to do this in the past with accounts that ive overused and abused but were not banned/warned and it helped out greatly.
