It often shadowbans for that, so you can still log in and read, but if you post, only YOU can see your post. Nobody else can see your post. It gives you the illusion that you posted.

One of the ways ppl knew if they were shadowbanned, was to open the post in a private window. But that will be harder now. The priate window won't be logged in, so you won't be able to look. And ofc if you log in, you'll see it, b/c that's what shadowban does. The only way will be to use an alt account to look.

The enshittification continues.
