Ah, good point. Thanks. I still like the idea, though. Content-based spam filtering has some catching up to do, and until that is a feasible approach I suppose that front-end measures should be considered. Perhaps image tokens can still be used with user registration as a fail-safe that also supports disabled users. At least, this could be an option for the site administrator if the feature is made available?
Where can I find WordPress’ mission statement where this is mentioned so I can keep up with things?
