One of the options for blocking people is to let them post on their own wall even when they're blocked from everything else. There are a couple of reasons for this. In cases where the problem might have been accidental, it lets the person discuss the matter with other people.

And there's the possibility that given even a limited chance to interact with other people, the blocked person will just go and continue the bad behaviour. "No, this person has not learned their lesson." In which case the block gets extended and the option of using their own wall also gets blocked.
