I made an account with Vlad in the username, and then i made another that was related to baseball. Both under the same email. To test it further, i made another account today using the same email and had the name Sankara in it. It is already shadowbanned. Fuck reddit.
there's a website that will tell you if you are, but heres how to tell for yourself: go to your user profile page where you can see your posts. Then log out and try to go to the profile page again. If youre shadowbanned it will say you dont exist or were deleted.
