I successfully created a few Gmail accounts changing the proxies through Firefox, after the 3rd account and third proxy, as I am using a separate proxy for each Gmail account, Gmail starts asking for phone verification. If I am under proxy how does Gmail know or why would they make me verify the fourth account on a 4th proxy. Is there something that lets Gmail know even though I am using a proxy that I am the same user? The computer itself or something? I downloaded Firefox with no information saved about me either which should make it different. All the proxies do have the same port if that is the reason why not sure? And some proxies have the same numbers but the last two or three are different after the last "." Anyone able to shed some light or give any pointers on how to go stealthier with this?
