An add-on that changes banning behavior:
Banned users can still view the forum, download attachments etc... they just can't post. I don't care if banned users browse the site I just don't want them posting anymore.
Give option to ban or soft ban users, soft ban = can't post or interact...
Easy User Ban allows you and your moderators (if permission is set) to easily ban and unban users without having to go to the ACP.
This Add-on also displays the banned users list.
Link to ban/unban users directly from their profile/member card/profile posts/thread posts/conversations...
