To me, it seems like you and deftnerd both have similar opinions. Where you fear the abuse of power, they fear a power imbalance. The social contract includes a distinct power imbalance to ward off a general power imbalance, which I construe as abuse, and I take it for granted that deftnerd accepts this contract. So while it seems that you lean more towards oversight and they lean towards preventative measures, you both seem to agree that this power of tracking malcontents is too damaging in a bad faith scenario to be vouchsafed.

That's why I stuck to your use of "improper only because of lack of good faith", to paraphrase. It seemed to me that you were willing to ignore not only the slippery slope argument, but also other forms of abuse such as harassing protesters at home, arresting bystanders, or identifying up exes' current companions.
