Ok, I do not care if they are known to PayPal. As long as I am good with AdWords then that is awesome.That's not a must as far as I know, however most VPS's IP ranges are well known to Paypal.
It's not a myth and even if it was it's better being than being sorry. You're not obliged to use a different VM each time as there are several tools that could help you spoofing the fingerprint and other informations your browser is currently sending to Paypal. You must have a separated cookie profile for each account and that's the easiest part, you can either use a browser extension or change your Windows user acount (assuming you're using Windows).
So, if the fingerprinting thing is not a myth then it would be best to use an antidetect tool or different chrome profiles? I do have unlimited VPS's to use so if that is best then I can do that. Can also get residential proxies. What would you recommend? Thanks again for the advice.
