How to remove accounts in a phpbb forum (in Off-topic)

Well this is the situation, cbstuff's forum is getting flooded with spam bot accounts being created.

I have now prevented them from being activated, so the spam has been stopped.
However I want to be able to remove the accounts from the forum completely.

How can I do this?

I dunno, I uninstalled phpBB and installed SMF. SMF has some spiffy forum features built in. I think SMF is a fork of phpBB with extra stuff added in.

SMF should work fine.

This is what the manual says:

Looks like there are a couple of ways you can accomplish it:

3.5.3: User Management

This panel will allow you to change settings and information for any user on your board. To use it, simply enter a username into the text field and click Submit.

This panel will allow you to edit any part of a user's profile. The panel is identical to the standard profile panel, with a few extra settings at the end. For more information, see 4.7 Profile Settings.

At the bottom of this panel there are Special admin-only fields that are not part of the standard profile settings.

User is Active - You may deactivate/activate a user. This is most often used to activate a user who is having trouble with email activation. A user may not log in while their account is inactive.

...

Delete this user? - To delete a user, check this box and click Submit. A deleted user's posts are converted to Anonymous posts with their old username as the name specified.
