@QasimRashid Follower count is also not reliable:
a) the instance can lie about follower counts of its own users however much it wishes (and also lie about the list of followers -- you can only sometimes verify that with the other side),
b) you can create an instance with 10k sock puppet accounts on it and have them all actually follow someone; if you are too blatant about it many instances will likely defederate from that instance, but (a) you can be subtler (b) it takes some time.
For these reasons, follower count on ActivityPub (and, I think, ~any decentralized social network) cannot be meaningful. What would be more meaningful is something like "how many of people I follow follow that account", but we don't have tools to show that ATM.
