===== Problem to solve
Some users can cause disruption by moving/renaming pages.
Social sanctions can keep them in check, but currently the only technical means to corral this type of behavior is a full site block, which is extreme for some situations.
===== Proposed solution
We should introduce a way to block a user from only moving or renaming pages. This will allow us to retain the user while they learn about wiki policies without blocking them off the entire website.
===== Acceptance criteria
* On Special:Block, under 'Actions to block' add a checkbox for `Moving pages`
** The checkbox should be unchecked by default
* When a block is saved with the 'Moving pages' checkbox selected, the target user should not be able to move a page via API or the wiki.
** Error messages should display appropriately (see below)
* When a Partial block is saved with the 'Uploading files' checkbox selected, the log items should indicate moving pages is part of the block
** e.g. //23:20, 26 November 2018 AdminUsername (talk | contribs | block) blocked BadUser (talk | contribs) from moving files with an expiration time of N (autoblock disabled) (unblock | change block)//
* Special:BlockList should display that a user is blocked from moving pages as a bullet in the 'Block parameters' column
===== Error message
For Special pages:
<strong>Your username or IP address has been blocked from moving or renaming pages. You can still edit other pages on this wiki.</strong> You can view the full block details at [[Special:MyContributions|account contributions]].
