I just tested it and the number of fans can be displayed. But this data is very inaccurate because we directly use all your scattered Relays. Every time you want to see the number of fans of an account, you have to re-pull the contact data of all relays to calculate the number of fans. The speed is very slow. Now only those clients with local cached relays can accurately know the number of fans of the user. You can query through primal and nostr.band, they use locally cached relays. This is the query data of nostr.band 🫂
