Multiple IG accounts with same URL

Hello, everyone
Would like to ask how you guys deal with the "website" of your IG account. I heard that IG bans multiple accounts which have same url/website.

I really don't want to shorten the link since my domain is unique... Is there other ways?

Maybe. Try to use the redirect from other domains. Example, <your domain>-1.com, <your domain>-2.com where will redirect you to you main domain. If you have enough money - you can try.

Or you can use other part ".com". Instead .com use .net/.org and other...
<your domain>.net
<your domain>.org

That's true, I had same domain name on 2 accounts, and they both deleted in one week..
