How to edit/extend/remove pager in the admin back-end? For example I just applied Mollom for antispam and everything, because the site got like 500 spam comments and 500 spam users. Now I can delete them only by selecting 50 users per page in the admin/people list and that is taking up really lots of time. I will have to remove comments and forum threads like that too page by page, 50 at the time? Would be nice to somehow extend those admin back-end pagers for various lists, like amdin/people or admin/content so I could select them all at once, or select at least 100 per each or something like that.

Maybe there's a module or something?
Views Bulk Operations was written to handle such situations:


  This module augments Views by allowing bulk operations to be executed on the displayed rows. It does so by showing a checkbox in front of each node, and adding a select box containing operations that can be applied. Drupal Core or Rules actions can be used.


You can build a View to filter users by whatever criteria makes sense, and use VBO to delete them all (not just those on the current page) in one go.
