Does anyone think something based on something like SMOG readability to check grade level + something like uClassify [or some other machine learning API for age:text correlation] would go a decent way towards fixing this?<p>For sites that actually care about this sort of thing and aren&#x27;t doing the legal minimum?<p>[i.e. Take a 500 word sample from the user over their initial posts, test it against SMOG to see if it meets a minimum grade level. Test it against a machine learning tool to see if it estimates reasonable age. If it doesn&#x27;t pass, disable the account and ask for ID and&#x2F;or parental consent form]
