Isn't Ghostery a better solution for something like this? If we are talking about browsers that is.

This uses less system resources.

Ghostery only works with the web browser. Other apps would be free to continue to embed such links or assets from those locations (and based off my own use of a hosts file, it's more common than I'd like to admit).

urlfilter.ini is even better, less resources
