This also means that one of my spam defenses is having a field that is hidden by CSS - if it is filled, it's a sure sign for a spammer... Nice one, good idea, but why not use a CAPTCHA?
Because they annoy real users.
Hmm, I guess they might. I'm not so sure - even casual polls on news sites are using CAPTCHAs.
I know they are occasionally also circumvented, but it requires a real person, which is a lot more effort.
I wouldn't be surprised if spammers use OCR, at least for the captchas that are not terribly readable
I'm certain they do, that's why the graphical CAPTCHAs are always twisted etc. -- Per Jessen, Zürich (12.3°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse-project+unsubscribe@opensuse.org To contact the owner, email: opensuse-project+owner@opensuse.org
