Every profile is public and always will be — a reputation service that hides its data behind a token is not a reputation service. What $DEV buys is speed and reach: alerts when an address you follow launches something, and a higher API rate.
Every profile, every metric, every proof link, and the open API at the anonymous rate.
A watchlist of addresses with alerts on the site when one of them launches, and a higher API rate. Proven by signing a message — nothing moves, no gas.
