Ultimate Wordpress Comment Spammer (My Personal Experience)

I've Been Using UCWS For About A Week Now....
I Used About 100 Proxies With About 40 Comments In Rotation , Scraped A Good Bunch of wordpress urls...

at the end it turned out to be useless...not even a single comment stuck ....infact just to make sure i was not posting on non-wordpress blogs...i even targeted my own blogs which are wp....
not even a comment came in spam....
so no moderation....
this got me thinking how effective ucws is or that its just plain crapware....
im buying scrapebox next week...hopefully it should stick on to the blogs...

about comment posting feature. boths have same function. UCWS support multithreads. scrapebox not.

I too do not see any that stick. I used a specific list of about 3k that i know will post and stick. And not one stuck, not 1. Am I missing something? Thanks guys
