You can also earn Satoshis for entering captchas! For each correct captcha you submit, we will credit your account with 100 Satoshis.
So the deal is help the spambots that flood the rest of the Internet with unwanted crap and malware links?
No thank you.
What?
I've been using computers since acoustic couplers were all the rage, I know what is going on.
When user does the captcha thing, a spambot that needs to solve one to post its spam sends the image to your server.
User solves it, spambot then posts it's spam or links.
One of the first incarnations involved porn, each one you solved the image showed a little less clothes until she was naked.
Now I guess tiny fragments of digital currency are used instead as incentive to get people to solve them.
Sites that are involved with that disgust me. It's everything that is wrong with the Internet today.
