Has anyone else noticed that the captcha words used by most of the social sites are more difficult to read than it used to be?? Sometimes I have to reload 3-4 times to understand the letters; there are times when the word is in mirror or when there are greek or other weird characters....
I personally prefer the Captcha that asks you to pick a word from a definition or add up a series of numbers. These are easier AND more effective at what they are designed to do, which is block spambots from filling out website forms. The whole letter/number thing superimposed on top of a bunch of sticks and twigs just doesn't seem very smart to me.
It is not the problem of social network! i observe everywhere that Captcha becoming difficult day by day
I have noticed this too on some sites it depends on the exact software the site is using - but personally I absolutely hate it and I usually try to avoid it as much as possible on my own sites. Recaptcha is not too bad for readability.
I agree! Spambots are ALWAYS and CONSTANTLY updating to the captcha's. Human's have the knowledge of entering a custom code to prove their "humanoid", rather than a bot. For a webmaster, It IS a lifesaver. They, as well as me, would rather have the human take another 2 seconds to F5 it, then for many bots to join and spam a website. This is just my view on it.
i have the same problem. i have to ask for a help before i can get the word. this irritate me sometimes but i do well understand why they have to do this.
I've noticed captcha's becoming more difficult across the web, just not specifically on social networking sites. It's got to do with smarter spam bots out there.
