This will greatly reduce the rate at which they are able to send the spam though, even if the delay is tiny. Similar to how bcrypt works.

No it won't, not if their spambot is multi-threaded. (Which all the good ones are.)

All it will do is increase the latency, the overall throughput will be pretty much unaffected.

Good point. Though keep in mind there are spam botnets with thousands and thousands of members.
