Something I’ve been thinking about is using onchain reputation to regulate decentralized exchanges.

For example, you only allow a wallet to even *place* a limit order if they link a yourname.eth with enough reputation.

Trade with Farcaster/Interface users only?

I think a single classifier turns into a game of cat and mouse, and it's hard to create a one size fits all model for protocols. Small composable classifiers are the way to go imo. As a dev, I can choose the onchain criteria for actors, e.g., deposited to Coinbase, has a Farcaster account, and claimed the ENS airdrop.
