Using a VPN for Tik Tok

I know you have to use one device per one account in order not to get shadowbanned but can I use as many accounts as I want on only one device if I use a different VPN for each accouny ?

I’m using 6 accounts per device logging in and out no shadow bans yet.

As the device itself and it’S connected identifiers doesn’t change this is a bad idea, arguably worse than using 1 device with a legit IP + 6 accounts as @John_Doe pointed out.
