It happens to all new accounts. It's known that new account are shadowbanned almost everywhere until they are 30 days old and farmed some karma on a very small set of subreddits that don't shadowban new accounts. It's shocking they ever get any new users, really; as far as a non-technical new user knows, nobody ever reads their comments for some reason.
It's full of bot slop pushing political propaganda, it's possible those bot farms have monetary agreements with Reddit to allow them to create accounts.
