probably virtual machines with different ip's
vmware workstation, or maybe hyper-v from windows server 2008/2012
VMs are a waste of time take the tinfoil hat off. I've had plenty of bots on the same PC others got banned from all on at the same time same ip no VM yet the 1st wave only 4/6 2nd wave 1/5 got hit.
Isboxer google it best way to multibox. What I would NOT do right now is use a leveling profile. level by hand or don't do it at all.
