Why do I, with a user-profile and logged in, have to do a reCAPTCHA again and again? It's pretty annoying, and as I see it, it should be enough to do it once at every new logIn. I can see the idea doing it several times with anonymous users.
Is there no way to exclude registered users? Maybe just ban the occasional offenders? Limit the captcha checks to newly registered users, and so on?
Also, how about limiting a number of searches per IP? Say, first search every 10-15 minutes is free, then activate a captcha check? Registered users get more searches before the check hits?
Really hope a better solution will be found. I love this website, but wasting so much of my time on captchas really gets on my nerves.
