[Defeat]

So guys I'm tweaking a method on Amazon but I get my acc banned.
This method requires multiple accounts a day to be created and used, and need to be anonymous ofc.
Up until now they have stated that I didn't follow their terms and agreements and once about linking the account to an already blocked one.

I am fully aware that the company in question is one of the wealthiest and most developed, but I have a vague understanding as to how they may be linking the accs and banning them.

IP Address
- This one is tricky with them, apparently you can't use a VPN because your payment method gets blocked instantly. Using Socks5 is apparently also bad because you get flagged or something.
So I changed my IP Address by restarting my internet modem and according to IP checkers it changed the IPv4 and IPv6.

Cookies
- For this one I think a CCleaner should be sufficient after the creation of a new acc, just clean the browser and I should be good to go again.

Mac Address
-I want to use a tool here after every acc created.

Account  Names and Passwords
-Apparently Amazon's security system can cross reference acc names and pass and should be able to find you because of the repetition of these values.

My question here is do you guys know of some Information that can be used to track me down and connect the accounts together?

Thanks in advance

Some of my own experiences:
I've used VPNs to order off Amazon no problem, that's usually only the case with gift cards when you're using a VPN from another country (only case I've seen it an issue)
Account names, ok that makes sense, but passwords? Someone who's more knowledgeable when it comes to encryption, maybe @vittring can comment on that. If they truly can cross check passwords, doesn't that mean they can decrypt them? Might sound super dumb but my understanding is encryption is not meant to be identical so if they can cross-check passwords, that either means they can see them or decrypt them? Clearly I'm not well versed in this sort of security
