During the last week I have been trying to PV lot´s of accounts by telephone, all of them using owned private proxies. I became really annoyed when I found out that only 1/5 of the accounts managed to be verified. The guy who run this service is 100% trustworthy, so I began to worry both about my proxies, and any suspicious activity on the accs. The only unusual issue I could find was that by going into FB security settings I could see that certain accounts were showing my real active location. I did not know if that was enough for not allowing the PV process (as far as I know, you don´t need to have a e.g. UK phone, UK proxy, UK active session location), but it was odd enough to become suspicious. As I have some experience in removing fingerprints, I first tried finding the trace. Before going further, I began removing any common tracking resources, changed mac address on both computers, made sure java script was disabled, safe private modes were enabled in browsers, diferent screen resolutions, ... I checked and tested all available addons (I run the accounts on different firefox profiles), but even supposedly blocking all FB tracking activity, my real location can still be seen on security settings as active. I tried every possible method I could remember but FB can still detect my real location in all tested accounts. Anyone is experiencing anything similar on their accounts? Do you know if there is any trick or workaround so I can PV those accs?
