How does Facebook track you

Did the following,
New MAC address, VPN, new e-mail address, new browser.. I just can't understand how I still can't create a new account.

What other unique identifiers are there?

You're using a VPN that's probably been utilized for doing all sorts of shady shit. If you get some decent, dedicated proxies, that should alleviate this issue you're having. Do keep in mind though that for account creation, you'll need some pretty good proxies if you want em to last. Most decent proxy providers will kick you off their plans if they find out you've been using them to bulk create accounts so be vigilant of that.

@GreyHatNik Thanks for that. It's probably why Tor won't work either. I'll look into proxies, I just need a second burner account and I'm having difficulties with even that.

Does anyone know if they block already created accounts(new or old) if you log in through vpns/tor?

Myself, I'm considering buying an aged account. But, I have no ideea to what extent they can track you? I would be logging said aged account from a location that I've already used to try and make accounts, behind a vpn mind you, but still - do they even track you through a vpn?

I know there's tons of variables(at least for me anyway) but I hust want to know to what extent their feelers reach. If I've just been unlucky because I kept using mainline VPN, then that's fine but if they corroborate info from cookies, location and keep building a map (AAAAAA) then I'm screwed.

Very strange that you do not get, try to buy a server and create on it

Have you checked that the VPN is clean or not? You can go to whoer.net to check this. Maybe your IP is on the red list

Just like you find this services, facebook can do the same.
They probally have a black list for services, so you'll just have to find the one the still consider "Legit"
Good Luck!

Chances are that the new things you prepare are already old FB stuff
LOL

You should use a anti fingerprint browser and a proxy for this job mate

very likely your VPN, and if its a cheap one just think about the amount of people that have used it before. You need virigin clean IPs preferably mobile 4G proxies
