EAB 3.7 contains a new set of tools to help clean up spam and deal with spammers.
Threads and posts can be selected in the usual inline moderation fashion, and then the new 'Delete Threads/Posts as Spam' command can be selected, which will load the spam management interface, which contains options on a single page for removing the spam posts and threads, banning the spammers and finding other spam they may have posted.
