I'm not a tech guy.
I see that some people around here are already satisfied with the captcha solution, which seems to have been proven successful in preventing bots or macros. While my language pair hasn't shown a difference in particular so far, the real problem I'm suffering from is that the captcha keeps asking me to click on several poor-quality images such as traffic signs, fire hydrants, etc., over and over again. On the first day, I just clicked the "I'm not a robot" checkbox and successfully got some jobs, but somehow it seems that Google detects something wrong on my PC.
Gengo's announcement states that it should not take long once you click the button confirming "you are not a robot." I'm not a robot and do not use one. I have discovered that Google's captcha solution detects users' suspicious activities based on not only automatic malicious traffic, as it should, but also on various factors such as the use of VPNs and ad blockers, IP addresses, and even browsing history.
In my testing, I have remotely accessed my office PC, used my wife's cell phones, and disabled VPN connection, but the captcha still keeps asking me to click on more and more images, as if I have already been blacklisted.
I'm simply hoping that the solution is working correctly. However, I kindly request that Gengo consider the possibility that it could negatively affects the user experience and harm innocent translators like myself.
