So even if I never directly access Etsy when using this proxy IP, you think there is a way for them to see I have used it on that browser?yes, the IP address is an important indicator of fraud, and it's definitely recorded for E-commerce website like Etsy
yes, why notCan websites see the past IP addresses you have used?
If i use IP #1 to warm cookies on a anti-detect browser profile, then switch to IP #2 and go on Etsy website, can Etsy see this IP #1?
