If each client has a copy of the filter, then so does the spammer. The spammer can use that to craft spam the filter doesn't catch.

The lack of filter availability doesn't stop spammers bypassing even Google's uber-filters, so it's not much of an argument really. The arm race is what it is. The point is having a system that can react fast enough to remove the spam from most systems once it is identified.

Then you need a system for distributing filter updates, and preventing the spammers from distributing bogus filter updates. Isn't this basically just the same problem as before?

That's why I said that injecting some modern consensus-finding strategies could be an idea.
