Last time I posted a question (about one year ago), I noticed that Stack Overflow had the "Are you human?" verification check with Captcha. Now, we seem to be able to just post questions and answers freely (as I noticed today).
How can you prevent against bots, then?

The captcha appears when huge amounts of text are pasted in a post body at once.
There are other things that trigger the CAPTCHA, and I will add them as I find them out.
