Affiliate Marketing Secrets

I’ve been caught up in the trolling efforts of a well-known firm that pursues possible pirates of pornographic films. I’m innocent, I’ve never even heard of the film and I don’t participate in piracy. I’m willing to offer my computer to be searched to clear my name, though they’re pressing for a settlement of a few thousand dollars before they publicly name me as a defendant (one of those ‘John Doe’ situations). Seeing as the best evidence they have is an IP address that was somehow affiliated with my internet account, do I even need to hire a lawyer for this?
