Account age is a lie

Dividing followers by account age punishes anyone who signed up, forgot about it for two years, and only really started posting last spring. So this measures active age instead: it reads your whole posting history, works out your normal rhythm, and finds the point where your current run of posting actually began.

The threshold isn't a fixed number of quiet days — it's derived from your own habits. Five weeks off is a holiday if you post twelve times a day, and business as usual if you post once a fortnight. Both get judged against their own baseline.

No login. Everything is read from public data: your repo comes down whole in a single com.atproto.sync.getRepo request — every post, no pagination, no sampling — and follower counts come from the public AppView. Results are cached in your browser. Clear cache
