account with BO2 purchased - already linked to plutonium account

[dwark17]

Hello, I am wanting to verify ownership of blackops 2, I had purchased an account that owns bo2 using G2A, the account works and everything but i was wanting to use plutonium with it. I have tried linking my steam account with plutonium, but it seems whoever i bought the account from has already linked the steam account to a different plutonium account so i was unable to link. If i do family sharing from that account to my main steam account would i be able to verify ownership that way? open to suggestions!

Yeah that should be fine, some games i hosted before like iw5 for pluto are game shared to me i dont own them so you should be good to share them to your main account and then link your main account to your pluto account
