Exactly. If a newcomer starts completely disconnected from everyone in the network, it’s indeed hard to enter the trust graph. But if they come to Nostr through someone they know, they can gain some initial reputation from that recommender, enough to help them stand out from the spam accounts.
How does an account get reputation? I like the approach but it typically leads to cold start problem

Do we already have a feature to allow invite someone to Nostr using Jumble, so they automatically create an account following the user who invited him?
It’s a good idea, but it wouldn’t help with the initial reputation issue. A new user would still need the inviter to follow them in order to gain any reputation.
