Just installed MT-Blacklist 1.62. Pretty easy -- a matter of a few clicks only. So don't panic when you are gonna hack your MT. Following the install instruction of user guide coz in most cases the authors have figured everything out for you.

It's kinda early to de-spam comments on my blog. Anyway, there are only 7 comments on it so far [and four were posted by myself]. Yet, keep it in mind -- the best treatment is prevention.
