Risks of Account Sharing?

[xxgotownedxx]

I was recently banned on my main, and was wondering if i could use a friends acc?
How risky is it to account share?
Me and a friend are looking to share an account, we live in the same state (about 120mi/190km apart), although he uses a different ISP.
Could I mitigate the risk by using a VPN? Then it would seem like one guy is just turning on a vpn?
Would we need the same exact .dat files?
Anyone know how severe the punishment is for account sharing? Straight perma or temp suspension?
Would it be a problem if someone attempted to login while the other was playing?

Thanks in advance for your point of views .
