It is sometimes rumored that spammers are using pornographic sites to solve CAPTCHAs: the CAPTCHA images are sent to a porn site, and the porn site users are asked to solve the CAPTCHA before being able to see a pornographic image. This is not a security concern for CAPTCHAs. While it might be the case that some spammers use porn sites to attack CAPTCHAs, the amount of damage this can inflict is tiny (so tiny that we haven't even noticed a dent!). Whereas it is trivial to write a bot that abuses an unprotected site millions of times a day, redirecting CAPTCHAs to be solved by humans viewing pornography would only allow spammers to abuse systems a few thousand times per day. The economics of this attack just don't add up: every time a porn site shows a CAPTCHA before a porn image, they risk losing a customer to another site that doesn't do this.

Pretty damn good idea lol. Who cares if it pisses off visitors, you're using the humans type ins for things like creating a new account somewhere or making a new spam post. Not trying to sell porn.

Works better to have a room full of Asians or Russians inputting captchas all day...

"Few thousand" times a day? Risk losing a customer? LOL... skim traded TGP traffic!

BTW this trick isn't new... I just think it's strange that the article (source?) seems to think it won't work.

It's just some excerpt from a page on recaptcha.net while I was grabbing a plugin for a form. Sorry can't find the page anymore.

I've never heard or thought of this method but it sounds decent, if I were a spammer.

They're probably right about it causing you to lose visitors but as long as you get your 1000 or whatever human type ins you need to overcome captchas seems like a great idea IMO.

Nothing new.... lots of people did it with web proxies as well. Every X pages a captcha pops up.

Getting captchas solved is cheap, I could pay $2 per 1k... and there are cheaper places.

indian workers are doing it for 1$ a 1000 captchas, you cant beat that

Found it on http://www.captcha.net/

Incidentally, when searching for that text I was presented with a captcha from Google.

I use tor (which uses anonymous relays/proxies) so my real human search queries probably get lumped in with a bunch of bots hitting google. All I want is a page of search results, but by entering that captcha I'm indirectly allowing those bots to continue...
