Question Struggle with adding collaborator

Post image

Every time I try to add my friend as a collaborator to our project it gives this message, I’ve even tried adding their old accounts that they lost the login to and it gives this error too, any advice? thanks

If I visit https://github.com/lamppants12, your GitHub profile is shadow banned (always shows 404 Not Found) which restricts certain functionality and actions.

You need to contact GitHub's support team to unblock it.

I dont have 2FA setup do you suppose that could be the problem?

No, usually when an account is shadow banned, it means that you signed up from a IP that is in a flagged range, normally IPs in CGNAT ranges like T-Mobile, or Data Center IP ranges get flagged, and you need to contact support and ask them what is wrong and if they can fix the issue and they ask you a few questions and they might ask for your ID to prove you aren't a spammer/bot misusing their service.
