"Why doesn't Farcaster have $0 sign ups"

Why doesn't Etheruem have $0 gas fees?

What if farcaster users can socialize the cost for new users? Basically like meta sponsorships and each user can show off how many new users they "sponsor"

I like pixels and scribbles, building /tavern  ⌐◨-◨  テ Φ

1. How do you determine who should get the sign up?
2. How do you prevent spammers / fraud?

1. I mean it's like patreon or hypersub but for any new users. Or like twitch subscribers that get donated. I don't get to pick I just donate money.
2. This is a harder problem to solve and I don't have good ideas for that haha

The only thing I can think of is a leaderboard of "users" that don't pay for an account yet but are in a setup phase. They can get "soft" sponsored by folks and donated funds get distributed top down. If your a sponsored account you can't soft sponsor any accounts, so no multi-spamming accounts to get free accounts.

2. If someone has a good solution for this, we’d be happy to pay for the experiment as Warpcast.
