multiple accounts-same computer problem

[Jacknife]

I reigistered with multiple accounts on one world, each one is operated by a different bot in a different folder from a different ip.
Yet somehow the game recognizes that they are all on the same computer, does this have something to do with the mac address?
Can I somehow circumvent that?

the same IP so even if you run accs in 2 bot instances game will detect that 2 accs are using the same IP
