The SpamUserPage gadget allows administrators to delete a userspace page, block the user, and issue them with a block notice, all in one click. It is mainly intended for use with user-page spammers or vandals whose usernames violate the username policy, but can be customised for a number of different scenarios where you might need to delete a user page and block the user.
It should go without saying that you need to be an admin to use this script. Non-admins can install it, but it will not work properly.
 | Make sure you know what you're doing before you block someone and delete their user page! You are responsible for following all Wikipedia policies and guidelines while using this tool, including but not limited to WP:BP, WP:DP, WP:CSD, and especially, WP:BITE. |
