Instagram CPA Domain

[Nic00B]

So i will start my IG journey soon, but i still have something unclear in my mind.I have bought a domain and a hosting, to host the locker.
Should i add the domain to all my ig accounts or that will raise a flag?
Also should i add a prelander or directly to my domain?
I tried tumblr prelander and i had lots of action blocks.

Use a prelander or a cloaker and shorten your link in different url shortners then add a unique short link to every account.

So one domain, one prelander and different url shortners on every account?
