The tactic will be to file lawsuits (or threaten to file) by the tens of thousands and settle for a few thousand dollars each.
Last year my wife got a certified letter from an out fit saying that 6 years ago we had purchased equipment that allowed us to view Dish Network without paying for it. They offered to settle for something like $5000. I looked them up and found that they were a real company pursuing cable/satellite theft. Problem was we had never done it or done anything resembling it.
Cost something like $700 in legal fees to make them go away. We basically had to prove we didn’t do it, and proving a negative is tricky.
