Hi,
Have we considered removing countries with low counts from metrics? (This probably means removing the metrics at the relays, not just the graphs.)
For example, two places that are close to home for me: https://metrics.torproject.org/userstats-relay-country.html?graph=userstats-... https://metrics.torproject.org/userstats-relay-country.html?graph=userstats-...
If you suspected that someone was one of the few users on either of these small islands, it would be easy to monitor these graphs and determine when they were using Tor.
Particularly in combination with the Australian Government's ISP-based metadata retention.
