Pff. That's like saying the government is spying on you because you saw a police officer look at you when you walked past a police car. Personally, I am just fine with the FBI harvesting the details of anyone who visits a CP site. So this puts strain on the network and causes loss of functionality for non-illegal uses of Tor - inconvenient, but then it's also inconvenient when you can't park because a police car, fire truck, or ambulance is taking up the space you hoped to park in. On a scale of 1 to 10, the harm suffered by non-criminal Tor users during this sting operation looks to me to be about a 1 or a 2.
