LionDollars for one, and we are not the only ones, have HIGHLY advanced fraud protection backed into our own merchant processing.
Sometimes fraudulent transactiosn are identified immediately, sometimes within 5 minutes of the same and sometimes can take longer.
Bottom line is that they are picked up FAST and immediate removal, blacklisting AND reporting happen instantaneously to any discovery.
This process works from our tracking and management and actually goes right back to our originating banks, where they progress immediate action for global blacklisting and reporting.
In this way, we directly help everyone out, because as the bank reports the details go on global blacklists for many other banks and processors.
