Thank you both, but I am using residential IP addresses and the problem should not be this. Even without proxy is still giving me the same errors. May be the addresses are pre-spammed already, or somehow it is managed to block my computers. That is why I am trying to pass the security of the site with the fingerprint + perfect canvas, but even this is not working. I have tried with other user agent settings also, but still did not work. I thought fingerprint + perfect canvas can solve this problem, and that may be I am doing something wrong, but looks like this is not the case.
