Humans regularly get CAPTCHAs wrong, and they often do so multiple times (if you have any elderly relatives, feel free to see how many tries it takes them to solve a reCAPTCHA one). Blocking them from even viewing your site for a day seems a little extreme.
+1 - there is one well-known blog site that uses capture, and I've tried as many as 10 times on a single submission, only to give up because I simply couldn't get the captcha right. Now I don't even try to comment there.
Is there an actual problem you're trying to solve here? Is there any indication that spam bots are affecting your site's performance? If not, worrying about this is probably a waste of your time.
We did have something of a problem on the userbase.kde.org wiki - mostly spam inserted on new user pages, but finally one destructive spam edit. We installed questy captcha for registration. It stops machine/bot registrations but not human ones. It doesn't stop humans adding spam, but believe me, the problem is so light compared with what it was.
