I pulled up the editing menu and discovered the fine folks at online casino [I.P. 212.78.66.136] left 500 comments. So I finally installed MT-Blacklist to do some preventative maintenance and housecleaning.
Please let me know if you encounter a problem with the comments.
Fortunately, some of us have done some of the work for you. I recommend you go here:

To see my list and add some of those domains to your own.
