Good thing you're not a P5 or they'd force you to be a Psycop. :P
Phanx, I'd have to agree there, hell just give a "get a high resolution of this challenge" button, then if the words are too hard to read you can still try it. I guess you're just stuck mashing the "get a new challenge" button till you get a clean one.
Whiner! The whole idea with reCAPTCHA is to put that squinting to good use. The words are ones that OCR software failed to recognize. The goal being that you not only protect a site that needs a captcha, but also help digitize books/papers/etc. Of course they make the assumption that they have some of the best OCR software out there, so if it can't read it it's unlikely spammer's OCR can either.
you do know how reCAPTCHA works, right Phanx? One word is "known", one is not. You enter both values, for the unknown one it saves your reply, for the known one it checks against the previous replies from other users. If yours matches theirs, they consider you to be as human as the other users were.
So if some users enter "1/4" and other enter "¼", well, you is screwed and have to try another pair of words. Granted, after the user enters a fraction in the reply for an unknown word, they could remove it from the database, but until at least one user has seen it they don't know that it's a fraction.
Its not laggy at all for me, using Flashblocker instead of noscript. But whatever suits you. We offer a choice for people that don't want flash.
Flash has had performance issues for a long time. Issues Adobe has admitted they are aware of and have never fixed. I don't even let Flash load (not FlashBlock, literally disabled) unless I close my browser completely and re-launch using a different shortcut. It's amazing (and sad) the performance increase you gain from this, no matter what your hardware is. Flash is shit, plain and simple. I'd much rather talk to a captcha than load flash.
