Can you get censored on farcaster ? Are there humans moderating and reviewing casts ? Or will it just be that your casts won’t have visibility and can only be found by scrolling your profile / search bar

Warpcast has moderation, Farcaster does not.
The Warpcast team has the power to make your posts or your account disappear from Warpcast, but not disappear from Farcaster.
Your posts will still show up in other Farcaster clients, unless these clients have moderation too and decide to follow the same decision.
