Question before i buy the new Forza

So i want to buy FH5 but i have cheated on FH4 with an other account and i got banned. My question is if i buy a copy with my account that i have cheated on FH4 does i will be instantly banned on FH5? Or if i need to buy it with an other account to avoid a ban
(of course i will not cheat on FH5 cause i regret what i have done on FH4)
And sorry for my bad english ;D
