X has already mentioned what they do in this regard. Posts that are excessively vulgar/crude/etc get shadowbanned. But it's the post, not the account. So if the guy wants to run around saying dumb stuff, it'll be seen by basically nobody besides those that follow him or otherwise actively seek it out. But if he decides to start acting like a normal person again, then his posts would work similarly to anybody else's.
