[racket-dev] spam & planet bug reports

You could implement your own captcha.  This is hard if the captcha is on 
sites popular enough to be brought to the attention of very smart 
programmers who specialize in compromising captchas.  This is easy if 
you don't have to worry about those programmers.

Or you *might* be able to use Recaptcha in a privacy-friendly way by 
serving everything yourself to the client, so that no HTTP request is 
made by the client directly to Google and no plausibly identifying info 
is otherwise propagated.  That way, privacy-wise, Google gets little 
more than timing and scale info.  I'm not sure that this is permitted, 
technologically or contractually.  Serving it yourself is also more 
expensive to maintain, and, in absence of guarantees from Google, there 
is more risk that what works today will not work tomorrow.
