You can download the current version of the Blacklist hosted by EllisLab by going to Modules > Blacklist in the Control Panel and selecting “Download pMachine.com Blacklist”.  ExpressionEngine will then download the latest list from expressionengine.com and update your own copy.

When EE updates your Blacklist:

- new entries in the Blacklist are appended to the end of your existing Blacklist
- existing entries you have made to your own Blacklist are not lost

Note: Before you can download the Blacklist, you must make sure you have your license number specified under Admin > General Configuration.
