Tracking computers in an online game

So, I have a problem with the fact that people make several accounts in order to make an account better with a large resource in the game.

So, my dilemma: many users go through a proxy or NATd, so some legitimate users will be blocked if I only have 1 user on ip.

Is there a way (with Javascript and PHP) to get a computer specific uniq identifier (without hardware changes, a hardware change would probably change the identifier).

Any idea or comments would be very helpful.

(The following was revived from an answer made by Paul, but was removed by another due to inappropriateness.)

I can’t change the client because its a browser game, so getting hwid would be possible. But as with JS or PHP.

Adding timers and restrictions to prevent transmission occurs, but does not stop them completely, it is possible to send emails to exclude IP. but it is slowly tiring. Im wonders if there is a specific generation of a specific identifier or identifier for a particular computer (not based on ip) that would force it to register multiple accounts from one computer, but can be registered from the same ip

Since we're talking about a different account, possibly on a different IP address and client, you cannot easily find clone accounts.

You can use two more heuristic and game options

I am starting an online games server. To prevent your dilemma, either change the game client to read the MAC address and allow only one account per computer. Or register ip and allow only the resources that will be provided to this ip twice. 3rd option: do not allow the transfer of materials from the same IP addresses 4th option: add a timer when transferring resources, make them wait 10 minutes of the game process before they can do something like getting rid of items for others to get
