Why don't you clean up "the bots"?

Useful to be precise here: "bots" is a catch all term that people use to describe low effort, uninteresting or otherwise off-topic content.

However, a "bot" is traditionally thought of as a programmatic account, i.e. controlled by a script or software. e.g. bot net

When people on Farcaster refer to "bots" they are more often referring to actual people using a mobile device (with the aid of translation tools and ChatGPT) who post uninteresting content (from their pov).

They are casting and replying in hopes of appearing to be a "real account" because they have learned that turns into a future economic reward in crypto. Recent tipping meta has increased the expected value of these accounts.

It's possible to algorithmically label these accounts, but then you create a "shadowban" meta. So you massively increase the number of support messages and complaints. This was the state of the world before priority mode.

I think being less transparent in what you are doing is far better in the long run even though it creates an uproar by a small number of people. 

Its easy to circumvent the rules when you know exactly what they are.
