This site will be the first stop for anyone wanting to harass another person online. Some times a little friction is a good thing. I love projects like these, but they're the digital equivalent of "dual use technologies". They can be used for good or evil. That said, nice work.
On the other hand, powerful people who wanted to harass you or hurt you have had access like this for a long time. It's how I feel about facial recognition technology or other ML-based technology too. The worst people who could ever have access to it, already had access to it. Giving everyone access to it is just leveling the field.
I'd love it if we could achieve that balance by eliminating surveillance, but I don't see that as a realistic outcome (at least initially).
In the absence of eliminating surveillance I'll take full public transparency. Maybe such transparency would even drive the elimination of surveillance.
