I think the negative remarks about LWB are from people not using it properly. I have been using it for about 4 months now and I have seen only good things from it. With little time to do white hat on one of my sites after a recent change of domain (lost all my juice, couldn't 301), i used this app to bring rankings back up in a competitive market.
Case Study: Recently I chose 200 keywords to target. I spread these targets across 13 new link wheels each ranging from 300 to 700 finished accounts. Ran them hourly for 5 days, then set them to run daily (spent about $50 in captcha

thus far). I run reports daily and then using a custom ping engine, I ping all the links created daily (I think this being NOT done is the biggest reason people think LWB is not working for them). After about two weeks of running I checked my search rankings. Using a custom tool to track search rankings against Google, Yahoo, Bing and AOL these are my results for the 200 keywords over the last few days. See the chart below of my results over the last 5 days. You can clearly see that ranks are going up daily. Again, the pages being ranked have very little matching keywords to what I'm targeting in the link wheels. Therefor I can assume my rankings for these KW's are mostly due to LWB.
