> The problem with recaptcha alternatives is that they either are insecure or require time and money to continue to be ahead of bots.
You're posting this in response to an automated recaptcha solver. Clearly recaptcha also has trouble staying ahead of bots.
It seems to me that any simple automated test at the entrance is inevitably going to be easy to solve by bots, especially when it's a one-size-fits-all test like recaptcha, so bots have only a single target to aim at. A small-scale unique test will be more successful simply for that reason.
But it seems to me that the better way than to ban bots together with humans who fail to pass your Turing test, is to check for the behaviour you want. If you don't want spam, have a system to recognise spamming behaviour, rather than traffic lights.
