While NodeBB does provide anti-spamming features, spam posts will occationally slip by.

Logged-in admins can edit or delete offending messages right away by clicking the 'gear' icon on any message. You can also create moderator accounts that are separate from the main admin group. In addition, we have user moderation tools which allow admins to to select multiple users to delete/ban them or to remove their topics/posts. We also have IP Blacklisting which will ban all users originating from a range of IP addresses.
