Ok, so you have considered: 1) Long names, and 2) Vandal names. But what about those non-vandal names that just seem inappropiate to be shown in a variety of pages or that just confuses users?

I had to delete this userpage of a user that hasn't done any edit on the wiki because some anons were editing his userpage as if that page were the real article. Think what would happen if names like that appear on every image thumbnail or gallery.

And another kind of usernames would be those not so unacceptable to ban them, but still totally off-topic or that just would confuse users. As I said, people that didn't notice that pages were written by real people, would also be confused about those names.
