This usualy happens due to "bayesian probability" algorithms in their chargeback prevention system.
from wikipedia:
"Bayesian probability is one of the most popular interpretations of the concept of probability. The Bayesian interpretation of probability can be seen as an extension of logic that enables reasoning with uncertain statements. To evaluate the probability of a hypothesis, the Bayesian probabilist specifies some prior probability, which is then updated in the light of new relevant data. The Bayesian interpretation provides a standard set of procedures and formula to perform this calculation."
In other words ( in the case of payment processors ) : based on a number of factors the software predicts that chances are really high that a chargeback will occur thus it does not allow the transaction...
I had this happening 2 times with zombaio... as a reason for the declined transaction it said "Bayesian probability"
... apparently these checks are very common in payment processor risk management software.
