Ebay tracking techniques:
+ webgl is the most important and dangerous data ebay would want from your browser: the result will be same for all chromium based browsers , and all versions of firefox browsers will have the same result.
Safari — the only browser that has the ability to Ask before running WebGL scripts on random websites.

+ Using real cc plus residential or mobile broadband IP make a strong account
+ VM is not good to create act: if they detect you are using vmware you will get immediate suspend, vmware can be detected easily in many way, vmware bios or the gpu driver name
=> We should not block ebay tracking but give it what it wants in our way 🙂
