I put a ticket into trac about this a few months ago.

https://trac.bbpress.org/ticket/779

Changing the way it functions is not too difficult but it does have to be done via the core so unfortunately I can’t address it via a plugin. At least I dont think I can, not easily.

Oh and forget a captcha ever being built into bbPress/WordPress. It will have to be done via plugin with a hook. Because the moment thousands of people have the same standardized captcha, that’s the moment it will be analysed to be broken by bots. As a plugin the method can be changed on a whim and vary from site to site easily. Besides, I’d rather have people do simple math than an awkward captcha.
