WP (Wordpress) Plugin To Modify Comments

Need a wordpress plugin that: - Automatically removes all the links, in any shape ([login to view URL], [login to view URL], <a href="[login to view URL]">Link text</a> etc) and every extention (com, org, info, etc..), from the newly added comments. - has a field line, where I can enter several keywords, separated by a coma, so the plugin randomly chooses 1 keyword and inserts it into a random location of the body of a comment.
