Loads of really helpful comments – thanks everyone 🙂

I’m seeing a lot of human entered spam on some sites which the honeypot method isn’t going to catch and Akismet often does. However for those really annoying automated posts that can flood in the honeypot method sounds to work well. So that’s another good option for people to try. Just make sure it’s obvious for people who do see the field that they should not fill it in!
