Farcaster Devs

Is there a way for a client to tag a cast with a flag that prevents other clients from indexing the cast?

Eg. say I'm building Hypercast, and I only want Hypercast to show certain casts. Right now, if a user makes a cast, and it gets sent to hubs, all clients will show this cast by default. Is there an alternative?

An interesting challenge! One solution might be implementing a visibility tag system, where the creator can specify which platforms or clients can index their content. This way, apps like Hypercast could filter based on these tags before displaying.
