Hi proxygo, I was thinking about the reason behind a problem I facing with using proxies in browsers.
I normally use Chrome for proxies with a proxy switcher addon. I always keep 10-20 proxies in the switcher and always check them at whatismyipaddress.com to make sure they are anonymous and not present in any spam database. I use them mainly for creating multiple accounts at Web 2.0s such as Tumblr or for creating email accounts for registering those Web 2.0s.
I close all tabs and delete cache, cookies etc. (shift+control+del) each and everytime before switching the proxy. I also run it on an anonymous window to be even safer. I test the proxy with whatismyipaddress.com before starting the registration at Web 2.0 to make sure the proxy is working properly. I only use those proxies which I am very confident about.
This works fine for sometime but I have noticed that Tumblr deactivates my newly created blogs during registration itself after I create say 20 different Tumblr accounts using the process. It again works after a day or so. Mail.com and Gmx.com detects it even earlier and blocks after creation of a few emails. Once the block starts, I cannot create any more accounts in browser irrespective of what proxy I use.
But when I change the browser to Firefox etc., everything works again for sometime til the process repeats. So, I was wondering if there is some other footprint directly attached to the browser which many websites can detect? How on earth do they detect that I am the one creating the account when I use proxies in different continents one after the other? I use different email providers etc. and so, there is no footprint there too. There is perhaps a footprint attached directly to the browser. Do you know of any and are there any permanent fixes for this problem?
