both captcha are not good but solvemedia is better because within a second you can change dificullty level of captcha
A word to the wise for whoever is using Solvemedia. Don't turn up the captcha to the highest difficulty. The captchas it spits out look like a grabled mess and are nearly unreadable by humans. I would say 1/10 a person can actually get correct.
Im using solvemedia on diff 3 out of 10 and i already need to refresh 3-4 times to be able to read it. But refs went down a lot!
Now i just got to solve the problem that adsense doesnt pay me a shit if no one clicks on my ads xD
