UseBB 1.0.11 changelog so far:
- Added possibility to remove user's posts upon removing user in ACP.
- Added possibility to ban user's email address or domain upon removing user in ACP.
- Fixed bug that didn't update stats on full forum delete.
- Added user delete link for admin on profiles.
- Removed ICQ status icons from profile.
- Hide "deprecated" warnings from PHP 5.3.
Most of the changes are to accommodate removal of spam accounts. Any posts of spammers registering manually or getting through a weak anti-spam question previously had to be removed manually. Now this will be with a simple click.
I will be testing it a bit more and uploading it on the public forums before a release perhaps later this month or April.
