Different IP addresses for bots running on different VMs?

Hello,

I plan to start leveling many League accounts through my self coded program. I will use VMWare with a virtual machine for each account. So every account will be played on a system with a different Mac Address and Hardware ID.

Since I'm not experienced in botting League accounts, I wonder if I should install a proxy client or VPN client on every VM? Does it reduce the chance of getting banned?

And if the answer is yes, can you recommend me some services? I already found some VPN clients but their free versions are very limited. But I am willing to pay for it if you say that it is worth.

Always a risk, but best option are vm's with other IP's.
I don't know a VPN-provider with multiple connections.

Always better with other IP's , i know good VPN provider but u can't run multiple,if anything helps his name is : Cyberghost, check it.

Honestly, it's not 100% sure that the same IP adress would cause a ban wave for other accounts, we don't know how Riot detects such accounts, the best you can do is to experiment with it a bit. :) Who knows, maybe the IP change wont be needed.
