@hrottie, this is indeed an issue, I imagine. Not entirely sure how one would stop it, especially since fake accounts would be created via mining and I don't know if IP address is info that the network receives. I would think that it would, but maybe internals don't save it or provide a mechanism to do so ... may not be possible without some significant refactoring of code.

Even then, IP spoofing is still possible at many different levels.

Not even an IP checker will fix it, because almost no one is on a static IP. However checking IP addresses, machine names and Mac addresses combined with Site cookies will drastically reduce fake accounts.

Yes but i think that is not the main problem.
If we have not fair people over here, with big account,they may constantly upvote new , fresh fake accounts and take out profit's from them.

Im looking for some way to fight this,any idea @complexring or anybody else?

I think only IP checker can win.
