'@login' spam exploit
A number of "online marketing gurus" have started using "@login" in their tweets, which exploits this script and shows them as replies on http://twitter.com/login.
To defeat this, add http*//twitter.com/login to the excluded pages:
Tools > Greasemonkey > Manage User Scripts
|Noecker Script's Author||
The script has been updated to ignore the login page without adding the explicit excluded page section. Thanks for the report!
