FileDefend.com was one of the first file lockers we took on and we hit them a number of times. Each time they came back with new payment processing we shut it down.
Once Alexa 5000, it is now offline, about a year after it started. Like FileMates.com, the site was a serious threat - experiencing exponential growth over a short period of time. However a sustained campaign of hitting their payment processing arrangements paid off.
Right now we are working hard on a number of targets, there will continue to be closures, terminations and mitigation and the possibility of criminal sanctions against file locker owners and operators, especially those residing in the United States, looms large.
