You can use a non-image alternative: Like a randomly generated 5-choice questionare. The questionare should be dead simple for humans but hard to translate for a spambot. something like: " to proceed please answer the following question: (a brief explanation why this question is a plus: there are bots imitating humans and this dumb questionaire helps get rid of them etc. etc.) Where do people store books? - grocery store - shelf - refrigerator - all of the above - none of the above " Make sure to swap the correct choice and the question so that it cannot be guessed by mere brute force.
