Kolotibablo is one of the companies that offer its workers from typing captcha. Kolotibablo has been around since 2007. This company has been paying its freelancers until now. Kolotibablo has also been one of my main sources of income since 2010.
The ability that must be possessed in kolotibablo is typing. As long as you can type, you can already earn from kolotibablo.
How much do we earn in kolotibablo?
Maybe the earnings look small between $0.38-$0.42/1000 Captchas. But along with our ability to recognize captcha and our typing skills our income will increase.
In 1 hour I was able to type around 10000 captchas by playing multiple accounts (permitted by the company as long as it doesn't use third party software) or about $1/hour.
So Kolotibablo is enough to provide a fairly good income, especially for developing countries.
