Is there shadow banning in github?

I created a new account and from that account opened a ticket on a repo.

For this ticket I have a valid URL. I can see the ticket information when I am logged in the new account. When I use an old account I get a 404 for the tickets URL.

Regardless of which account I use, I don't see the ticket in the repos issues list.

Did anyone else experience something similar?
