Badword blocker should have solved this need but the current badword blocker doesn't work as it should so I am requesting a new plugin.

A word blocker that will not only block a specific word everywhere on the site but also inside of URLs posted to the news feed.

example setup: word to block, "google" - word to become "mysite"

example 1. "google" --> becomes "mysite"
example 2. "www.google.com" --> becomes "www.mysite.com"

this way if you have a repeat url spammer the news feed won't parse his link and post a link to his target site. Great for anti spam

Please help!! Can anyone make this simple plugin?
