Is it okay to have two accounts that don't interact, or can I be banned?

Basically the title. Just want to know if I could play on two accounts but without EVER transferring anything between them or even interacting at all, just two completely different playing experiences as if I was two people lol. But could they ban me because of device? Or for using a parallel app to add a second account even though I won't be abusing it to get more stuff, I just want two diff collections 😔 (yeah I know it's weird but don't ask why trust me it's just that reason and I'm just weird lmao)
