Well, I signed up for a Pacer account and started looking into some Masterfile cases. I was delighted to come across this case, "IT Machines, LLC vs. Masterfile Corporation, NCS Recovery Corp. and Phusion 25". Looks as if someone had the cajones to stand up to Masterfile and fire a shot across their bow. As far as I can tell from reading the docket, it was related to the Fair Debt Collection Act and was subsequently dismissed. Unfortunate, but at least it looks like Masterfile had to squirm a little bit.
