Who gives a crap...seriously?
While most everyone here will get their panties in a bunch this really isn't a big deal. You can get caught a crap load of times before anything actually happens and under this system you get a heads up that you got pinched (without you having to admit anything) so you can change your methods for pirating should you choose to ignore the warnings.
And seriously, what percentage of people will be wrongly dinged? A fraction of a percent and then so what? They click through and in a second they're back off doing whatever they're doing with a notice that they may want to check the security of their home network to make sure they're are no leeches or their kids aren't DLing a bunch of crap.
Seems perfectly reasonable to me.
