I know there are ways to detect and avoid anonymous proxies by simple scripts, but if I surf a website which doesn't block the proxy I'm surfing on, does this mean the website does not detect my proxy? I am using vtunnel by the way. Is it true that surfing by vtunnel doesn't make you 'look anonymous', but only replaces the IP you are surfing with?
So if a website registers my fake proxy IP, can it know that I was surfing by proxy afterwards? Especially when I fill in forms and such? Are the webmasters able to know that I was surfing by proxy after seeing the IP afterwards?
