My main concern with keeping anonymity is with what they'll do with your information, even after "settling". I read once that someone settled and they were continually harassed by these people (or this person) for further settlements. What was not made clear was whether the further claims were for repeat offenses, or if they were somehow able to dig up more dirt on this individual and continue to extort.
I'm sure that probably hundreds of these notifications are sent out weekly, and honestly, could this person really pursue all of these cases, or even half of them realistically? I want to say this is a scare tactic that is designed to make them money in the process of deterring piracy. In all honesty, it has scared me straight. But I'm not so sure of what I think about the threat. I've read there are people 3 and 4 months into not settling and nothing has come up. Does anyone know, exactly how long does this person have to pursue each of these claims of copyright infringement? Forever? Is there are window of time allowed? Any idea?
