How is user reputation calculated? I understood that as people with a higher reputation follow others with a lower reputation, their reputation increases, but how did these more reputable users get a higher reputation at the beginning?
The last feature of https://jumble.social/ in 2025:
A reputation filter that hides notes from the bottom X% of users by reputation.
It works across feeds, notifications, and replies, and is especially effective at reducing spam when browsing large public relays. #devstr

Everyone starts with the same score. The system then recalculates reputations iteratively, and after enough rounds the scores converge and stabilize.
