Different devices for each Instagram account?

I bought 20 aged accounts yesterday and on the website it had a "best practices" page to not get the accounts banned. Most stuff seemed pretty straightforward; warm up, mimic human behaviour, use proxies etc.

But I didn't quite understand or know how to implement one piece of advice. It said if you log into multiple accounts use different devices.

For example let's say I'm on a VPS using proxies and the account threads are running at the same time using GMT2, is that against the advice?

If so, do I get a program to make it appear like the accounts are on separate devices?

In order to log in to Instagram (using the private API), a device ID is REQUIRED. That means GMT2 will generate one for each account. So you should be fine.
