How to delete all topics and posts from a user/spammer in myBB?

This is a tutorial on “how to delete all topics and posts from a user/spammer in myBB”. Please check out the answer.

I use the Goodbye Spammer plugin for MyBB.

First, install it after downloading the plugin form its homepage:

1. Upload ./inc/plugins/goodbyespammer.php to ./inc/plugins/
2. Upload ./inc/languages/english/goodbyespammer.lang.php to ./inc/languages/english/
3. Go to ACP > Plugins > Activate
4. Go to ACP > Configuration > Goodbye Spammer Settings > Configure settings > Save

Then you can delete the posts/threads of a user as follows.

1. Open the user/spammer editing page as an Administrator or moderator or users in a group allowed in the option of Goodby Spammer plugin.
2. In the “Moderator Options” tab, click the “Use the Goodbye Spammer tool on this user” link.
3. Then you can ban and user and delete the posts/threads created by the user. Be very careful here since it may deletes many posts/threads.
