Let's say you are using firefox portable + storm proxies and you are doing manual click and search. Can google detect you are using proxies ? Meaning you are not using public proxies. Has anyone here tested this ?
use tmac and change your mac address after that use proxy for every click and search. That may be helpful but it takes your time.
Every week, there's at least one thread with this idea. No, it won't work for you. It's been tried, tested, everything, it doesn't work. It can even work as a form of negative SEO actually.
